Great picture quality and smooth performance
Style: 2026 Model, Size: 65-Inch, Style: 2026 Model, Size: 65-Inch
This Toshiba 65" Mini‑LED TV has been a great upgrade for my living room. The picture is bright and clear, and the colors look very natural. The 144Hz refresh rate makes movies and games feel smooth, and Dolby Vision IQ works well in different lighting. The built‑in Fire TV is easy to use, and the sound with Dolby Atmos is better than I expected. Overall, it’s a solid TV for everyday watching and gaming.

Good quality
Style: 2026 Model, Size: 85-Inch
I am extremely impressed with this Toshiba 85” mini LED TV. The picture quality is absolutely stunning. Sound quality is better than expected for a flat-screen TV. The built-in audio is clear and immersive, and Dolby Atmos adds a nice sense of depth without needing an immediate soundbar upgrade.
The Fire TV interface is easy to use and responsive, with Alexa built-in for convenient voice control. Setup was quick, and streaming apps run smoothly without lag. This TV feels like a premium product at a great value for its size and features, if you’re looking for a larger-screen TV with excellent picture quality, strong gaming performance, and smart features, this is definitely a great choice

Good audio system
Style: 2026 Model, Size: 55-Inch, Style: 2026 Model, Size: 55-Inch
I got the 55-inch model to replace an older Hisense 43A6 that stopped working, and I'm happy with it. The bigger screen is nice and movies look much better and speakers even better than on my old TV, especially at night. It was also easy to set up since I don't want to spend a lot of time with settings. The sound quality is better than I expected. More than good enough for normal use. Overall it feels like a solid upgrade from what I had before.

Great Picture, Easy Setup, Awesome Value
Style: 2026 Model, Size: 75-Inch, Style: 2026 Model, Size: 75-Inch
Really happy with this TV so far. The picture quality is awesome - super bright, colors pop, and the contrast is way better than I expected (the Mini-LED makes a big difference, especially at night).
The 144Hz is smooth for games, and everything feels responsive. Movies look great too with Dolby Vision - very sharp and detailed.
The Fire TV interface is simple and fast. Setup is super easy - just connect to your Amazon account and a few clicks on your phone, and you’re done. Having Alexa built in is a nice bonus.
Overall, feels like you’re getting a lot for the price. Big screen, great picture, and solid features. No regrets 👍

Switched from Sony and honestly surprised
Style: 2026 Model, Size: 65-Inch
Been using Sony TVs forever, so I was a little skeptical when I made the switch. But honestly, ten days in and I keep finding myself just... sitting down to watch something because the picture looks so good. The colors are genuinely impressive — rich without looking overdone. HDR content especially looks great, deep blacks and bright highlights without that weird bloomy halo effect I've seen on other TVs.
I've watched movies, binged some shows, and played games on it over the past week and a half. No complaints on any front. Gaming feels smooth — the 144Hz panel makes a real difference and the TV switches modes automatically which I didn't even notice until I looked it up.
Sound is better than I expected too. I kept waiting for it to fall apart on dialogue or get muddy during action scenes, but it stays pretty balanced throughout. Still have my soundbar but haven't felt the need to plug it in.
The Alexa integration is probably what I use most day to day. One time I was already in another room and realized I'd left the TV on — just told Alexa to turn it off without getting up. Small thing, but that's exactly the kind of convenience that makes you actually appreciate it.
If you're coming from a Sony like me, the adjustment is basically nothing. Genuinely happy with this one.
