We purchased this tv for a guest room, looking for a 32 inch model with built-in Amazon Fire functionality, 1080p resolution, a decent remote, and a reasonable price. This one seemed to check all the boxes. The tv arrived in one day, well-packaged and in perfect condition. Set-up was very simple.
This TV is perfect for what I wanted. I wanted to get a fire TV because it included the amazon app store, which is incredible. All the streaming apps I need are included in this store. I originally got the 24" Insignia TV, but I found it just a little small from the distance I had to place it, about 8 feet away.
