Great entry level 4k TV
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This TV has a great picture. Its priced as if it isn't a 4k TV. Not as impressive as some 4k TVs at twice the price but for the price it can't be beat. Plus for me the selling point was having 5 HDMI ports. Very nice as most only have two. Comes with most mainstream online apps and easily connects wifi. Could be even better with more apps such as HBOGo, Showtime Anytime, etc.

Wish it had built-in wifi
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I chose SB6121 over other options because it had the highest rating in Comcast approved modems list for my connection speed. The modem performs as expected; set it up and forget about it. I only wish it had built-in wifi, but the price makes up for this.
