Really happy I bought this!
5 Stars
Really happy I bought this!
When we were notified that Time Warner would start charging us a lease fee for our cable modems, they gave us the option of buying our own from an approved list they included in the notice. I was a bit put off we had to use the ones they approved of, but this one had a lot of good reviews and it was a great price, paying for itself in a short time over leasing the cable one. It installed so very easy, the included CD was easy to use, step by step, any beginner could do this in a snap! I called Time Warner to activate it and it was up and running within 5 minutes. Nice looking as well, I like that is stands on its own and the slim design takes up very little space! Cant go wrong with the price and how easy it installed.
