Major upgrade

[This review was collected as part of a promotion.] I've been really impressed with the quality of this TV. The picture is incredibly sharp, the colors look vibrant, and everything just feels like a major upgrade from my previous TV. As a big soccer fan, one of my favorite things has been watching games on it. The movement looks smooth and clear, and the picture quality makes sports so much more enjoyable. I'm also a big action movie fan, and this TV has made movie nights at home feel like a completely different experience. The dark scenes, colors, and details look amazing, especially with action movies. Overall, I'm really happy with the TV and the upgrade in quality has been noticeable from day one.

Great Tv! Great picture quality and very light

[This review was collected as part of a promotion.] I really love this TV, it's the largest TV that I've purchased for myself, and I was really surprised by how light and thin it is. My old TV was much smaller, but it made my room so hot. This TV doesn't really emit any heat, so I can watch TV for as long as I want, without having to block out sunlight or crank up the AC I've been really enjoying the screensaver mode, it's nice to have the TV on in the background without having to watch anything, it just adds to the vibe of the room. There's also a large variety of live channels to watch if you do enjoy live TV. I was really pleased with the selection of live anime channels to watch which can substitute for a subscription. Lastly, I'm really happy with how sturdy and responsive the remote is. There isn't any lag when I use it, and I've dropped it a few times, and the back hasn't gone flying, which is really nice!
