this modem is cheap small and fast! saves me 10 dollars a month on my rip off cable bill so 120 year =) It sets up fast with a simple phone call to TWC and you will probably notice a performance increase over thier old beat hardware immediately. Especially if they have you on a old docsis 2 surfboard or one of them crappy ubee's. Basically just buy one you wont regret it.
TWC recently increased the lease fee for their modem to $10 per month. The fastest speed available to me is Extreme 50/5 Mbit/s, so this modem was perfect for me.
Easy to set up, stays cool and is stable. It saves me $120/year and I couldn't be more pleased.
