I reviewed the market extensively for a wireless mesh system for my new 5000 sq.ft 2 floor + basement house and finally landed on this one. With AT&T gigapower fiber in the house, I wanted a device which would support faster speeds, reach all over the house and also give me the flexibility to move around as needed. After researching Eero (expensive), Google Wifi (not enough throughput for me), Orbi (liked it but expensive), Velop (seems another good one), Milo (not enough throughput), Nighthawk (extremely powerful but only one device and was concerned about total reach on all floors and basement), I landed up with this Amplifi device. The device is sleek, setup is easy and everything can be controlled from the app, which is extremely convenient. Also the two additional antenna type devices plug in to wall outlets and keep coverage across the house. There are a number of features I like about this device: (1) internet control for kids, (2) device prioritization for streaming (3) dual band automatic switching based on where I am in the house (4) guest access control and expiry (5) ability to move the mesh around to the farthest corners of the basement (6) route prioritization (7) performance checks without the need for okla...the list goes on. In some areas I am getting close to 780 Megs/Sec download speeds, in others as low as 180 Megs/Sec, but for someone who had Xfinity 100 MBPS and was getting only 30-40 gigs in the past, I am a very happy camper. Especially, since I have cut the chord on my cable and only use online on-demand TV. And no more phones at home, just my cellphone which uses wireless inside. I have 2 phones, 3 tablets, 3 TVs, 1 Apple TV, 1 Roku, 1 Alexa, 2 desktop computers + guests who use the wifi network, and it runs without a glitch. Streaming is awesome and there is never a blip, thanks to this device. In fact, I keep it hidden even though it looks awesome and from inside the cabinet it works. And it is less expensive than many. I love it and would recommend it to anyone who is looking for a device that provides good coverage, good throughput, flexibility to move the mesh around, sleek and easy to setup at a less than $350 price point.
