    Excellent All-Around Performance

    I purchased this smart TV and have been thoroughly impressed. From the moment I unboxed it, I knew I'd made a good choice. The picture quality is excellent—colors are vibrant and the image is crisp and clear. Setup was refreshingly easy; I had it up and running in minutes without any complicated steps or frustration. The performance has been consistently great, with smooth navigation and responsive controls. The size is perfect for my space, striking that ideal balance between immersion and practicality. I was also pleasantly surprised by how lightweight it is, making it simple to mount or reposition if needed. Whether you're upgrading from an older TV or buying your first smart TV, I'd confidently recommend this model. It delivers solid performance without unnecessary complexity.

    Whoa!

    We purchased this last month after our 10 year-old Toshiba conked out on us. We wanted something that had good parental controls and decent picture picture quality. Well, we already knew the parental controls well as we have a different Fire TV, but the picture quality is way better than we expected! We caught the TV on sale and set it up the next day. The remote is very easy to use and the voice access is extremely convenient. I honestly have nothing negative to say about this TV. If I needed another one, I’d buy the same exact model. It’s currently used in a guestroom/office and is the perfect size. Extremely lightweight, and gave us no issues with set up or install installation. I’ve already told half of my friends and family that if they’re in the market for another TV, this is the one.

    TOSHIBA fire tv 4K

    This TV is an absolute game-changer. It is incredibly easy to use because I am already accustomed to the setup for Amazon Fire TVs. I currently have three Fire TV Cubes, and I needed an additional unit to replace a TV without having to change my entire system. By using just this one unit, I was able to do away with one of my existing devices, which saves me money. For reference, here is the information on the specific model I bought: - Product: Toshiba - 43" Class C350 Series LED 4K UHD Smart Fire TV - Brand: TOSHIBA / Fire TV 4K - Model: 43C350NU - SKU: 6618499

    A nice TV for the price.

    I bought this TV for my son to take to school. It is a perfect size for his available space in his dorm. He uses it for regular TV viewing and video gaming. He says there's no lag while gaming or watching sports, and the picture is nice and clean. All the built in and downloadable apps are great too. I'm particular and wish it had a full remote with a number pad so when using certain apps you could just enter the channel you want to go to instead of needing to scroll to it, but it comes with the standard fire tv remote.

    Great TV and Sale Price.

    Very pleased with our new TV. No need for a separate Fire device with Prime built in to the TV. The internal storage for apps has been increased from our previous Toshiba Fire TV from 5 GB to 10 GB. Excellent picture quality and brightness. The sound quality is typical but we purchased a separate Bose speaker which greatly improved the sound. Purchased when on sale for a $120 savings.
