I bought this to replace a Motorola modem that would occasionally lose it's connection for a few seconds, which is terrible for video conferencing. I was surprised by how small this modem is - it's half the size of the Motorola (see the photo to compare). Setup was easy and the UI has similar functionality to the Motorola. Best of all, I've been using this modem for a month now and have not had any loss of connectivity. It has been rock solid. Speed test show that I'm getting 1.22Gbps downstream and 51.8Mbps upstream, which is slightly better than the 1.2/40 that Comcast promises.

works as expected. getting speeds at 1200mbps per comcast plan. Honestly, this product is dead simple... screw in the coax and plug into router. most of the time the issue isn't with the product, but calling your ISP to activate it. Been running 24/7 since I bought it. no issues.
