Summary: Time Warner was going to begin to charge us every month for their modem we'd had since eternity. So it was time to give it back to them. Good decision. This was really easy to switch out and works fine.
Summary: I grabbed a modem to avoid renting one from Comcast and this one's been treating me pretty well. I was apprehensive about it only being 2.0 certified, but it's working just fine. I wouldn't have bought it at the price it is now, though.
Summary: I bought it to replace the modem (same model) I was renting from my cable company. Essentially, I've had two of these modems & haven't had any issues in 5 years. Works excellently & is much cheaper than renting the whole time.
Summary: Pros: Cheap used price since its an older DOCSIS 2 model (which only supports up to 38 Mbit/s) Works fine for my 15 Mbit/s connection (TWC Standard) Cons: Not as future proof as the more expensive DOCSIS 3 modems but I'll worry about that when those plans become for affordable
