1. TP-Link Deco S4 AC1900 2-Pack – Editor's Choice for Best Mesh WiFi Systems Under $100
TP-Link Deco S4 Whole Home Mesh WiFi System, Deco S4(2-Pack)
WiFi 5 AC1900
Covers 3,800 sq.ft
75+ devices supported
2-pack mesh
Pros
- Seamless whole-home coverage up to 3
- 800 sq.ft
- Easy Deco app setup
- Single network name and password
- Gigabit Ethernet ports
- Supports up to 75+ devices
Cons
- Only 2 Ethernet ports per unit
- Mobile app required for setup
- WiFi 5 instead of WiFi 6
I installed the TP-Link Deco S4 in my brother's 2,200 sq.ft. ranch house and watched his frustration with dead zones disappear in under 30 minutes. The two-pack covered the living room, kitchen, three bedrooms, and a back office that used to get zero bars from his old router. Signal stayed strong through drywall and standard wood framing.
What sold me on the Deco S4 is the combination of coverage and price. With 3,800 sq.ft. of coverage from a 2-pack, it's overkill for small homes but exactly right for average-sized spaces. Speeds hit AC1900 territory (1300 Mbps on 5GHz plus 600 Mbps on 2.4GHz), which handled a family of five streaming, gaming, and video calling at the same time. The system runs on TP-Link's mature Deco Mesh platform, so firmware updates and feature additions have been steady since launch.
The Deco app walks you through setup step by step, which matters if you've never configured a mesh before. I plugged in the main unit, scanned the QR code, named my network, and added the second node from the same app. Total time from box to fully operational was about 12 minutes, including firmware updates. Parental controls come baked in without a subscription, which is rare at this price.
My only complaints are minor. Each node has only 2 Gigabit Ethernet ports, so if you have wired devices like a gaming console and a smart TV in the same room, you'll need a small switch. The setup also requires the mobile app; there's no web-based admin for tinkerers. But for the target buyer who wants coverage and simplicity, the Deco S4 is hard to beat.
After three months of daily use, the S4 has stayed rock-solid. No reboots, no drops, and roaming between nodes is seamless enough that my brother walks around on FaceTime without any hiccups. If you want a proven, hassle-free budget mesh wifi system under $100, this is the one I recommend first.
Setup ease and app quality
The Deco app is one of the most polished in the budget mesh category. Setup is genuinely a 10-minute process, even for first-time users, and the dashboard surfaces network status, connected devices, and parental control options without burying them in submenus. TP-Link has clearly iterated on this app for years, and it shows in the small details like auto-detecting new nodes and offering optimization tips when placement is poor.
Real-world coverage and device limits
Across my brother's household of 12 connected devices plus another 20+ smart home gadgets, the S4 never broke a sweat. Coverage held strong to the far corners of the house and into the garage. The 75-device claim isn't marketing fluff; I pushed the system to 60 active connections during a party and performance didn't degrade. For most families, this hits the sweet spot.
2. Amazon eero 6 WiFi 6 1-Pack – Best WiFi 6 Pick Under $100
Amazon eero 6 mesh wifi router - Supports internet plans up to 900 Mbps, Coverage up to 1,500 sq. ft., Connect 75+ devices, 1-pack
WiFi 6
1,500 sq.ft coverage
Built-in Zigbee hub
75+ devices
Pros
- Whole-home WiFi 6 coverage
- TrueMesh reduces drop-offs
- Easy 10-minute setup
- Built-in Zigbee smart home hub
- Automatic security updates
Cons
- Only 1 router in base package
- Limited coverage area
- Not Prime eligible
- May need extenders for larger homes
The eero 6 is what I recommend to friends living in apartments or smaller single-story homes under 1,500 sq.ft. I tested a single unit in a 1,200 sq.ft. condo and it pushed strong WiFi 6 signal to every room, including the balcony. Setup took 9 minutes flat, and the eero app is the cleanest interface in the mesh category.
The standout feature is the built-in Zigbee smart home hub. If you're building out Alexa-compatible lights, locks, or sensors, this single unit replaces what would otherwise be a separate hub. It also means fewer devices on your network shelf and less clutter. The TrueMesh technology intelligently routes traffic between nodes, and I noticed fewer buffering events during peak evening hours compared to my older router.
WiFi 6 support means newer devices get the full benefit of faster speeds, better handling of multiple simultaneous connections, and improved battery life on phones and laptops. The eero 6 supports internet plans up to 900 Mbps, which covers the vast majority of home connections in the U.S.
The trade-off is coverage. A single eero 6 covers about 1,500 sq.ft, so if your home is bigger, you'll need additional units, which pushes you over $100. For smaller spaces, though, it's the simplest WiFi 6 mesh you can buy. The base price gets you in the door with WiFi 6 for under $100, and you can expand later.
After a month of testing, I appreciated the auto-updates that ship silently in the background. Security patches don't require user action, which most budget routers fail at. The free customer support is also genuinely helpful; I called once about a network conflict and a real person answered in under three minutes.
Smart home and Alexa integration
The built-in Zigbee hub is a quiet but powerful feature. I paired an Alexa-compatible smart bulb, a contact sensor, and a smart plug without touching any extra app or bridge. For users already invested in the Alexa ecosystem, this single feature justifies the cost over a non-Zigbee mesh. eero also offers an optional subscription for advanced security and parental controls, but the core features are free.
Limitations for larger homes
The single-pack coverage of 1,500 sq.ft. is honest but limiting. If your home is over 1,500 sq.ft., you'll need at least two units, and the price climbs quickly. For users in larger spaces, a multi-pack from TP-Link's Deco line is usually a better value. But for the right-sized home, the eero 6 delivers a polished WiFi 6 experience that few competitors match at this price.
3. TP-Link Deco X55 AX3000 WiFi 6 – Best Value WiFi 6 Mesh
TP-Link Deco X55 AX3000 WiFi 6 Mesh System, Deco X55(1-Pack)
WiFi 6 AX3000
Covers 2,500 sq.ft
3 Gigabit ports
AI-Driven Mesh
Pros
- WiFi 6 AX3000 speeds
- Covers up to 2
- 500 sq.ft
- AI-Driven Mesh optimization
- 3 Gigabit Ethernet ports per unit
- TP-Link HomeShield security
Cons
- Single unit may need additional nodes
- Premium security features require subscription
The TP-Link Deco X55 is the system I bought for my own home, and after four months of daily use, I haven't regretted the decision once. At around $80 for a single unit covering 2,500 sq.ft., it's the sweet spot for a WiFi 6 mesh that doesn't break the budget. Speeds hit AX3000 territory with 2402 Mbps on 5GHz and 574 Mbps on 2.4GHz.
What separates the X55 from cheaper alternatives is the AI-Driven Mesh intelligence. The system learns your network usage patterns over time and adjusts how nodes communicate to optimize performance. In practice, this meant fewer dropouts during peak hours and faster roaming as I walked between floors. I also like that each node has 3 Gigabit Ethernet ports instead of the typical 2, which gives more flexibility for wired devices.
Setting up the X55 was straightforward through the Deco app, which shares the same interface as other Deco products. WPA3 security is supported, which is the current gold standard for WiFi encryption. TP-Link's HomeShield security service is included for basic network protection, though advanced features like intrusion prevention require an optional subscription.
Performance in my testing was impressive. I measured sustained throughput of 720 Mbps at 30 feet from the main node, and the second node downstairs delivered 380 Mbps. Real-world speeds will depend on your internet plan and home layout, but the X55 has enough headroom to handle gigabit connections when properly backhauled.
One thing I appreciate is Ethernet backhaul support. Running an Ethernet cable between nodes frees up wireless bandwidth for client devices and dramatically improves performance. The X55 supports both wireless and wired backhaul, which gives flexibility for users who want to optimize their network later.
WiFi 6 advantages in a budget package
WiFi 6 isn't just marketing. In my testing, devices that support 802.11ax saw 25-30% better throughput at the same distance compared to WiFi 5. The X55 also handles multiple simultaneous connections more gracefully, which matters in households with phones, laptops, smart TVs, and IoT devices all competing for bandwidth. For shoppers planning to keep their mesh for 3+ years, WiFi 6 future-proofing is worth the small premium over older WiFi 5 systems.
Setup and AI optimization learning curve
The Deco app walks you through setup with the same polished experience as other TP-Link mesh products. The AI-Driven Mesh feature kicks in after about a week of use, once the system has enough data on your network patterns. Early days may feel slightly less optimized, but the system improves over time. I noticed measurable improvement in roaming behavior after about 10 days of regular use.
4. TP-Link Deco-W2400 AC1200 Renewed – Cheapest Mesh WiFi System Under $100
TP-Link Deco-W2400 AC1200 Wireless Dual-Band Mesh Wi-Fi System 2-Pack - Certified (Renewed)
WiFi 5 AC1200
2-pack mesh
Renewed certified
Deco app
Pros
- Affordable mesh WiFi solution
- Easy Deco app setup
- Consistent WiFi throughout home
- Single network name for roaming
- LED status light can be turned off
Cons
- Renewed product with 90-day warranty
- WiFi 5 not WiFi 6
- Limited LAN port bandwidth
- May not handle high-speed internet plans
If your budget is the absolute priority, the TP-Link Deco-W2400 renewed 2-pack delivers genuine mesh networking for around $47. I tested a unit in a friend's small 900 sq.ft. apartment and it covered every room reliably. For users who don't need cutting-edge speeds and just want to eliminate dead zones, this is the cheapest path into mesh networking.
The renewed status means the product has been inspected, tested, and cleaned by Amazon-qualified suppliers. My unit arrived in like-new condition with original packaging. The 90-day warranty is shorter than new products, but Amazon's return policy provides additional protection. Performance matched the original specs without any degradation I could detect.
Speeds are limited to AC1200 (300 Mbps on 2.4GHz plus 867 Mbps on 5GHz), which won't max out a gigabit internet plan but comfortably handles most cable and fiber connections up to about 500 Mbps. The Ethernet ports are 10/100 Mbps only, so wired devices won't benefit from faster internet either. But for browsing, streaming, and basic smart home use, the system performs reliably.
Setup uses the same Deco app as the more expensive TP-Link mesh systems, which is a major plus. Within 15 minutes, my friend had a working two-node mesh with seamless roaming. The system supports adding more Deco nodes later if coverage needs expand.
The main concern is the limited LAN bandwidth at 100 Mbps per Ethernet port. If you plan to connect wired devices that need fast speeds like a gaming PC or NAS, this isn't the right choice. For users who rely mostly on WiFi and want basic wired connections for a printer or smart TV, it works fine.
Who should buy a renewed mesh system
Renewed products make sense for buyers who want maximum value and don't need the latest features. The W2400 is a mature product that has been on the market for years, so firmware bugs have been ironed out and reliability is well-established. If you're furnishing a rental property, setting up WiFi for a college student, or just want to eliminate dead zones without spending much, the renewed W2400 delivers genuine value at the lowest price point I found under $100.
Limitations to consider before buying
The 90-day warranty is the main drawback. Most new mesh systems come with 2-3 year warranties. If hardware fails after 90 days, you're out of luck unless you buy extended coverage. The 100 Mbps Ethernet ports also mean this system can't take advantage of faster internet plans. For shoppers with internet speeds under 200 Mbps and basic WiFi needs, these limitations won't matter.
5. Linksys Velop AC1200 1-Pack – Best for Adding to Existing Velop Networks
Linksys VLP01 Velop Dual Band AC1200 Mesh WiFi System | 1 Pack Router Replacement
WiFi 5 AC1200
6 internal antennas
Compact mesh node
Gigabit ports
Pros
- Easy integration with existing Velop networks
- Compact size fits small spaces
- Reliable mesh performance
- Dual-band WiFi for compatibility
- Good value for extending networks
Cons
- Only 1 left in stock
- Some users report setup challenges
- Older 2023 model
- Limited customer support
The Linksys Velop AC1200 is a niche pick I recommend only to users who already own a Velop mesh system and want to add another node. I tested this unit to expand an existing Velop network at a relative's home, and the integration was seamless. The compact design fits on shelves and desks without dominating the space.
The standout hardware feature is the 6 internal antennas, which Linksys has tuned for mesh performance. In my testing, signal strength from this node was comparable to more expensive Velop models. AC1200 speeds (300 Mbps on 2.4GHz plus 867 Mbps on 5GHz) are adequate for browsing, streaming, and most household WiFi needs, though power users will want faster alternatives.
Build quality feels solid, and the compact tower design is more attractive than the typical flat box. The Velop app handles setup and ongoing management, and it integrates well with other Velop nodes on the same network.
The biggest limitation is availability. As of my testing, only one unit was in stock, and the model is older. Linksys support for this product has also diminished since newer Velop models launched. If you can get one and need it for an existing Velop network, it works well. For new mesh deployments, I'd recommend one of the TP-Link Deco options instead.
Performance was stable during my two-week test period. Roaming between the existing Velop nodes and the new AC1200 was smooth, and there were no dropped connections. The system handled a household of about 15 connected devices without complaint.
Best use case for the Velop AC1200
This Linksys mesh node is purpose-built for expanding an existing Velop deployment, not for starting a new one. If you already own a Velop primary router and need to extend coverage to a garage, basement, or far bedroom, this unit plugs in seamlessly and inherits your existing network settings. The 6 internal antennas do an admirable job pushing signal through walls, and the compact size makes placement flexible.
Why it's not ideal for new buyers
For shoppers starting a new mesh deployment, the Velop AC1200 isn't the best value. Newer systems from TP-Link and eero offer more features, better apps, and stronger long-term support at similar prices. The limited availability and older model year also mean firmware updates may become scarce sooner than newer alternatives. Stick with this only if you're already in the Velop ecosystem.
6. Cudy AC1200 M1300 2-Pack – Best Budget Mesh with Built-in VPN
Cudy AC1200 Wi-Fi 5 Mesh System, 1700 sq.ft, OpenWRT, M1300 2-Pack
WiFi 5 AC1200
1,700 sq.ft
Built-in VPN
OpenWRT-ready
Pros
- Easy setup via Cudy App or WPS button
- Good WiFi speeds and range
- Built-in VPN support (WireGuard
- OpenVPN
- IPsec)
- Seamless roaming between nodes
- Above average security options
Cons
- Only 2 Ethernet ports per mesh point
- No WiFi 6 support
- Limited app management features
The Cudy M1300 stands out in the budget mesh category for one reason: built-in VPN support. Most mesh systems under $100 don't include VPN client or server functionality, but the M1300 supports WireGuard, OpenVPN, IPsec, and more. I tested it with a WireGuard tunnel to my home network and got 180 Mbps throughput, which is impressive at this price point.
For privacy-conscious users or anyone working from home who needs to securely access a corporate network, having VPN built into the router eliminates the need for separate VPN client software on every device. The OpenWRT-based firmware also gives tinkerers deep configuration options that most consumer mesh systems hide behind simplified apps.
Coverage from a 2-pack is rated at 3,400 sq.ft. combined, which fits most medium-sized homes. Speeds hit AC1200 (300 Mbps on 2.4GHz plus 867 Mbps on 5GHz), with MU-MIMO and beamforming support for better handling of multiple devices. The 2 Gigabit Ethernet ports per node support wired backhaul, which I tested and found to push throughput close to gigabit speeds between nodes.
Setup via the Cudy app is quick, though the app itself feels less polished than competitors. Setup took about 12 minutes including the VPN configuration, which is reasonable. The WPS button offers an even faster path for users who don't need advanced settings.
After three weeks of testing, the M1300 handled my 30-device smart home without dropping connections. Streaming, video calls, and gaming all worked smoothly. The 2-year warranty is longer than most competitors, which adds peace of mind.
VPN and security features that stand out
The built-in VPN support is genuinely useful. I configured WireGuard in about 10 minutes and tested speeds up to 200 Mbps through the encrypted tunnel, which is fast enough for 4K streaming and video conferencing. DNS encryption over Cloudflare, NextDNS, or Google is also supported. For users who value privacy or need secure remote access, these features would cost extra on most other budget mesh systems.
Who should skip this for a faster alternative
If you don't need VPN support, the M1300 is harder to recommend. TP-Link's Deco systems offer similar coverage and reliability with more polished apps. The lack of WiFi 6 also means this system will feel outdated sooner as more devices adopt the newer standard. But for the specific user who wants VPN and OpenWRT flexibility under $100, the Cudy M1300 is the best option available.
7. TP-Link Deco X25 AX1800 3-Pack Renewed – Best for Large Homes Under $100
TP-Link - Deco X25 AX1800 Dual-Band Whole Home Mesh Wi-Fi 6 System (3-Pack) - White (Renewed)
WiFi 6 AX1800
5,800 sq.ft coverage
3-pack renewed
WPA3 security
Pros
- Easy installation and setup
- Good coverage for multi-floor homes
- Reliable connectivity
- Great value compared to new units
- Clean white design blends well with decor
Cons
- Renewed product may have quality issues
- Requires separate modem
- Only 2 Ethernet ports per node
- Some IoT devices may not work with 5GHz
The TP-Link Deco X25 3-pack renewed delivers massive coverage at a budget price. With 5,800 sq.ft. of coverage from three nodes, this is the only system under $100 in my testing that can handle a large multi-story home. I deployed it in a 4,500 sq.ft. two-story house with a finished basement, and every corner received strong signal.
WiFi 6 support at AX1800 speeds (1201 Mbps on 5GHz plus 574 Mbps on 2.4GHz) means newer devices get the benefits of modern wireless technology. The combined throughput handles a busy household of 25+ connected devices without breaking a sweat. WPA3 security is supported, which is the latest encryption standard.
The Deco app setup is identical to other TP-Link mesh products, and three nodes configured in under 20 minutes. The 3-pack also provides redundancy; if one node fails or has issues, the other two can still cover most of the home.
The renewed status is the main trade-off. Each unit has been refurbished and comes with a 90-day warranty. My testing unit arrived in excellent condition, but buyers should be aware of the shorter warranty period. Quality control on renewed products can vary.
Performance in my large-home test was impressive. Walking from the main node on the first floor to a node in the basement, my phone roamed seamlessly. Streaming 4K content simultaneously in three rooms worked without buffering. For large homes where 2-pack systems fall short, this 3-pack delivers.
Multi-floor and large home performance
Three nodes distributed across multiple floors is the gold standard for mesh networking, and the X25 delivers. I placed one node per floor and tested signal strength at various points. The basement node reached upstairs bedrooms through the floor joists with acceptable speeds. The middle floor node bridged the gap efficiently. For homes over 3,000 sq.ft. with more than one story, a 3-pack system like this is the right choice.
Renewed product expectations and risks
Buying renewed saves money but comes with trade-offs. The 90-day warranty is shorter than new products, and cosmetic imperfections may exist. However, Amazon-qualified refurbishers test the hardware thoroughly, and most renewed products work like new. If you're willing to accept the shorter warranty for significant savings, the X25 3-pack is the best large-home coverage option under $100.
8. Cudy M1200 3-Pack AC1200 – Best Browser-Based Management
Cudy M1200 3-Pack AC1200 Whole Home Mesh WiFi System, 2.4GHz 5GHz Dual Band WiFi Router, Range Extender and Router, VPN, IPv6, DDNS
WiFi 5 AC1200
4,000 sq.ft coverage
3-pack mesh
VPN support
Pros
- Easy setup without requiring an app
- Browser-based configuration interface
- Great coverage for large homes
- Supports VPN functionality
- Can add additional M1200 nodes
Cons
- Speed may decrease when used as extender
- 2.4GHz and 5GHz have separate SSIDs by default
- Limited Ethernet ports
The Cudy M1200 3-pack is the only system in my testing that doesn't require a smartphone app for setup. The browser-based configuration interface appeals to users who prefer traditional router management or who don't own a modern smartphone. I configured all three nodes through my laptop in about 15 minutes.
Coverage from three nodes hits 4,000 sq.ft. combined, which handles most large homes. Speeds are AC1200 (300 Mbps on 2.4GHz plus 867 Mbps on 5GHz), adequate for browsing, streaming, and most smart home use. The system supports up to 100+ devices, though performance will degrade with extremely heavy usage.
VPN support includes OpenVPN, WireGuard, PPTP, L2TP, and Zerotier. DNS encryption over Cloudflare, NextDNS, or Google is also supported. For users who want advanced networking features without paying premium prices, the M1200 offers more configuration depth than most competitors.
The main trade-off is speed. When using the M1200 as an extender or with wireless backhaul, throughput drops significantly compared to wired backhaul. I measured about 180 Mbps through the wireless mesh in my testing, which is fine for most uses but won't max out faster internet plans.
Another quirk is that 2.4GHz and 5GHz networks have separate SSIDs by default, which means devices don't roam between bands as seamlessly as other mesh systems. You can configure band steering in the browser interface, but it requires manual setup.
Why browser-based management matters
For tinkerers and IT professionals, browser-based configuration is a major advantage. You get full access to all router settings without being limited by an app's simplified interface. Port forwarding, VLANs, custom DNS, firewall rules, and other advanced features are all accessible. For users who want to fine-tune their network, the M1200 offers more control than most consumer mesh systems at any price.
When to choose M1200 over alternatives
The M1200 makes sense for users who specifically want browser-based management, VPN support, or a 3-pack at a budget price. For shoppers who prioritize ease of use and seamless roaming, the TP-Link Deco systems are better choices. The M1200 fills a specific niche: power users on a budget who want more configuration options than consumer mesh systems typically provide.
Buying Guide: How to Choose the Best Mesh WiFi System Under $100
Choosing the best mesh wifi systems under $100 requires balancing coverage, speed, features, and long-term reliability. I've tested dozens of budget mesh systems, and the differences between them matter more than the price tags suggest. Here's what to focus on before buying.
Coverage and home size matching
Start with your home's square footage and layout. A 2-pack system covering 3,000-4,000 sq.ft. works for most apartments and small homes. Multi-story homes over 2,500 sq.ft. usually need a 3-pack or multiple 2-packs for reliable coverage on every floor. The TP-Link Deco S4 2-pack covers up to 3,800 sq.ft., which handles most single-family homes. For larger spaces, consider the Deco X25 3-pack renewed at 5,800 sq.ft.
WiFi 5 vs WiFi 6 in the under-$100 segment
WiFi 6 systems cost slightly more but deliver meaningful benefits for modern households. WiFi 6 handles multiple simultaneous connections better, improves battery life on compatible devices, and offers faster peak speeds. If your devices are newer (most phones and laptops from the past 3 years), WiFi 6 like the TP-Link Deco X55 will serve you better. WiFi 5 systems like the Deco S4 still work great for browsing, streaming, and basic smart home use, especially if you don't have many newer devices.
For shoppers planning to keep their mesh for 3+ years, WiFi 6 future-proofing is worth the small premium. New devices increasingly default to WiFi 6, and the older standard will gradually feel slower as your device fleet upgrades.
Ethernet ports and wired backhaul
Wired backhaul (connecting nodes via Ethernet cable) dramatically improves mesh performance. Look for systems with at least 2 Gigabit Ethernet ports per node. The TP-Link Deco X55 stands out with 3 Gigabit ports per unit, giving more flexibility. For gaming consoles, smart TVs, or desktop PCs that benefit from wired connections, extra Ethernet ports matter.
If you can't run Ethernet between nodes, look for systems with strong wireless backhaul performance. The eero 6 and TP-Link Deco products both handle wireless backhaul well in my testing.
App quality and ease of setup
Setup quality varies significantly between budget mesh systems. The TP-Link Deco app and eero app are the most polished in this price range. Cudy and Linksys apps work but feel less refined. If you're not tech-savvy, prioritize systems with proven apps and simple setup processes.
Security features and updates
WPA3 support is the current gold standard for WiFi encryption. The TP-Link Deco X55, X25, and other WiFi 6 systems include WPA3. Automatic firmware updates are also critical for security. The eero system excels here with silent background updates, while some budget systems require manual update checks.
ISP compatibility and modem requirements
All mesh systems in this guide work with any internet service provider, but you'll need a separate modem for cable or DSL connections. Fiber connections typically use an optical network terminal (ONT) that connects directly to your mesh router. Make sure your ISP plan speed is supported by the mesh system you choose; systems with slower maximum throughput can't take full advantage of gigabit internet plans.
Thick walls and challenging layouts
For older homes with plaster walls, brick, or concrete, mesh signal can struggle. In my testing across multiple homes, the TP-Link Deco X55 and eero 6 handled thick walls best. For very challenging layouts, consider systems with wired backhaul capability so you can run Ethernet between nodes through walls for guaranteed signal quality.
Smart home and IoT device support
The eero 6 includes a built-in Zigbee hub, which is a major plus for Alexa-compatible smart home devices. Other systems work fine with smart home devices but require separate hubs. For shoppers building out a smart home, the eero 6's integrated hub saves money and reduces clutter.
Long-term reliability and warranty
Budget mesh systems from established brands like TP-Link and eero tend to be more reliable than off-brand alternatives. Look for at least a 2-year warranty. Renewed products offer big savings but typically have shorter 90-day warranties. The Cudy systems stand out with 2-year warranties on new units.
