    I've had this TV almost a month, several months after my old TV died. I ordered online, & they brought it out to my car in 2 hours. My Samsung was excellent, so was surprised this Insignia's picture is so good plus sound quality also good. I have it in a LR corner facing a big window, & I get no glare whatsoever. However, I paid $159, & they dropped the price $20 the next week. So it's definitely a good buy now.

    I like the tv because it was ok at the time but there was some things that I didn’t like meaning the volume had to turn up to get into the show or movie. Meaning too hear what they said.
