improvement over leased device
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I really resent the cable Company and their constant rising prices and made up charges. I decided to take some control and buy my own modem. I am very satisfied and would recommend this product to everyone. One less charge on the Cable bill' Easy to install and I get better streaming performance than the old modem.

Perfect for what I needed
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Overall, this product is perfect for what I needed to do. Just living in an apartment and didn't want a very expensive modem but one that was reliable and this one is not expensive but still great quality. Haven't had any problems with it. I previously had a NETGEAR and this is equally as good.

Works like charm for beginners
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I was pretty much unsure which one to get and then a friend of mine referred this to me. I have been using this with my Apple Airport Express WiFi router and it works like charm. You plug it in, confirm all lights shows up and connect WiFi router ... bam .. it works. Never had issues, and its working 24x7.

Great for Time Warner
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This modem works great for Time Warner. The cost is absolutely worth it. Why not pay one time for a modem than pay monthly for modem you will eventually pay for 3-4 times over depending on how long you have internet? I have never had any compatibility issues with routers. Its great.
