    • Great TV at value price.

Very good. Easy set up and great picture.

    • Change those factory settings unless you like “energy saving mode”
Size: 50-inch
Helpful advice to other buyers: This television seems like a standard HD television because from the factory they have it set to “energy saving model” which means the picture isn’t that good until you simply tweak it in the settings, also it’s quite bright so you can turn on adaptive lighting smart intelligence mode and that solves that. Don’t be afraid to buy this great television, it’s Made In Mexico I noticed when unboxing it, it’s very light weight approximately 22 pounds for the 50” we purchased, it’s got good sound and great picture I would consider this over an OLED not just for budget but I think the QLED technology which this particular budget friendly television has is better overall. Hopefully it’s reliable, I’m satisfied with my purchase but yes tweak those factory settings unless you want to save a tiny bit of energy and you will see a nice vivid picture in no time. ... show more

    • Sharp Picture & Sound

I was looking for TV that had a good quality sound/volume. This one is perfect. Setup was simple, and the value exceeds the quality.

    • Too breakable and confusing
Size: 50-inch
Very nice but very breakable. First, it was to be delivered in July but it appeared on my porch while I was gone early, not on the delivery date but before it. Got lucky as it set there for a few days. The damn thing slipped off the bed it was being prepped on. It broke and that was that. The instructions are very confusing as they do not show what the coordination numbers are between the plans and the screws. Toshiba is a brand I will never use again after I replace the broken one which goes into the garbage. ... show more

    • Get a soundbar
Size: 43-inch
Picture quality is fair, responsiveness to inputs is okay, setup was fine. Feet dont feel fully secure even after tightening down. My biggest gripe is the built in speakers, quality is terrible. Get a soundboard with it
