This was one of the best purchases I've ever made. Turned a blank wall in my bedroom, into a huge entertainment screen for a very reasonable price. The only complaint I would have with it is that it doesn't produce great sound quality, to compare with how nice the picture is. So I would suggest getting a real speaker setup to go with this awesome purchase. Football sunday will never be better.

I ordered these for my husband. We ordered based on the sizing chart and they were too big. He needed them right away so we ended up returning. We would order again but would go with his normal size. Usually he wears and XL but the size chart recommended 2XL.

Absolutely amazing product. Definitely helps in relieving back pain and correcting one's posture. Also, it comes with all these additional helpful things. Highly recommend.
