    Buy this if you can utilize the 3.1 DOCSIS speed

    Bought this for Comcast and it was very easy to setup. Just plug it in and follow the directions to activate it through Comcast's portal. Didn't have to talk to anyone from Comcast. I'm currently paying $70/month and I didn't want to pay the extra $10 rental fee. I sold my soul and locked in that price for 3 years. This modem and a good ac1900 router will pay for themselves after 1.8 years for me. The throughput on the modem is great, I'm getting the most out of my internet speed. I posted screen shots of a few speed tests. Since this is the only DOCSIS 3.1 modem on the market, at the time of writing this review, it is quite expensive. Luckily there was a promotion with VISA checkout and I had some rewards to use, this came down to a decent price. Because of the price, I wouldn't recommend this modem if you're internet speed isn't over 200-300mbs down. You may get incremental increases, but it wouldn't justify paying so much more for this modem compared to a good 3.0 DOCSIS modem.

    NETGEAR CM1000 - Amazing Speed!

    I had been using a Cisco modem with a TP-Link Archer C7 router for quite a few years, then decided to run some speed tests on it. They were good, and I was happy with the performance. However, saw there were some new modems out there, and maybe I could squeeze more speed out of one of those - if it wasn't better I'd return the new one and continue with what I had. Well, this Netgear is like a device out of Star Trek - it's heads, tails, and a mountain faster than the old Cisco I had. It wasn't cheap, but I'd buy it again in a second, and have recommended it to all my colleagues. I don't have any super-high-speed plan, but once I hooked this modem up and ran Speedtest, I was getting approximately 575 mbits/sec sustained downloads! Uploads weren't much different, but no one expects them to be. The key to satisfaction for me is download speed, and I couldn't be more satisfied with this modem. It looks nice, doesn't give me any problems with Xfinity - IT JUST WORKS AND WORKS FAST! I'd recommend this unit to anyone who wants to make their Internet work fly! Besides that, I no longer pay a rental fee for the modem - BONUS!!!
