    I ordered this on Prime day 2021. I had been looking at new televisions for months. I like this one. It ended up being my selection because of price weighed against size and features.

    I bought a new camper and planned on buying a small television to install in it. I found that I could buy a larger set cheaper than a small one.

    I replaced a an older set in a bedroom and moved it to my camper I personally don’t like the extreme high definition units. I have a curved súper definition tv in a vacation home and it makes everything appear like a Telemundo novella in my opinion. When the definition of the tv is so great that watching “The Boys “ made Elizabeth Shue look her age I was dissatisfied. Ultra high definition is not a friend for the actors my age.

    Movies and tv series need to have a bit of fantasy. They pay makeup artists for a reason.

    I really like the remote. I am a prime subscriber, I’ve had a Netflix account since back when they mailed DVD’s, I’ve got Hulu, and Disney+. The remote has built in quick navigation buttons for all four.

    I work in a highly technical field so in my search I was checking refresh rayes and a bunch of specs that many consumers don’t have a clue about. This unit has exceeded my expectations. **** I’m not a sports watching guy **** My colleagues had been advising me about what to look at for live sports. That doesn’t matter to me. When it comes to sports I’m a participant; not a spectator. Therefore, I can’t speak to that.

    Unboxing and setup were pretty simple. Read the instructions and don’t throw things out because they’re packed efficiently.

    I had a choice when ordering of waiting a few days or pickup at my nearest Beat Buy. (80 mile round trip for me) I wanted it right away so I chose to pick it up; plus there’s a Red Robin a few hundred yards from the Best Buy. (It was closed due to lack of help from the pandemic, but I got my TV. and not my onion ring!

    I’ve done a few tweaks to picture and sound settings today. Not that they needed it , but as a tech guy I want to play with the settings. It’s smart, but not so smart that the average consumer is paying for stuff they’ll never use. I don’t have a sound bar hooked up. I don’t need it. I’m not a gamer so features that support that aren’t in my wheelhouse.

    What I have is great picture., super out of the box sound, and an acceptable price. No buyer’s remorse If you need the latest and greatest tech this isn’t your set. If you want really good picture and sound with an easily navigable remote. A sleep timer that works great all at a reasonable price then click buy now.

    However, if you’ve looked at a pile of sets and have it shipped to Best Buy; I suggest doing a screenshot on tour order. The Amazon system doesn’t marry seamlessly with the Best Buy system so if you’re ordering during heavy order periods you’ll need tour info from Amazon to make finding your order in their stack of hundreds they pulled fo smoother. The Best Buy order and Amazon order numbers aren’t the same. In my case I didn’t remember exactly what I purchased and trying to look it up while the free wifi and multiple network providers just slowed the order lookup process.

    Replaced a 40" seiki that went out from 2012 & was really surprised to find out how much free content there is on fire tv. The picture between 1-10 is a 7 (could have a wider color array apparently from reviews I watched, looks more vibrant on dynamic setting or custom), sound is a 9 (great bass & treble.) Tubi, HULU, PLUTO, IMDb tv & HBO Max, Music + local I'm good. Already had an Amazon account & Hulu, HBO Max. TV looks great for $271 total. I say it's a steal, being that it's a Toshiba is one of the reasons I bought it knowing their quality, that said pretty sure Toshiba has been more high end until now, has a Toshiba badge but says Best Buy on the back of tv.. so take that for what it is but still really happy with this purchase. Btw, just got an offer for the Amazon echo dot 3rd gen for $5, $40 normally (they really want everyone to use them to buy more Amazon stuff). Now I can just tell Alexa to turn on the TV, listen to music, order stuff ect... so other many things without hitting the remote mic button. Hung it on the wall with a adjustable mount (a must to be able to angle tv down/swivel) Only 17 lbs! Looks great.

    I’ve had this TV for a few years and it has worked really well for me so far. I wish the speakers were in the front instead of on the back of the tv but that is a personal preference. I haven’t had any glitches or any other issues.
    Reviewed in the United States on October 17, 2020
    It's an OK TV and that's OK with me.
    I was not looking for something spectacular for $200. The TV met my expectations. Make sure you set your expectations right before buying this product or you'll end up here writing negative reviews.
    I want now to address some complaints that I read from other buyers.
    1. The TV is very light. I can easily carry it with one arm. The stand legs are fine too. Some people complain that the stand legs are thin and not sturdy. They are thin, but they are metallic and very sturdy.
    2. The picture is good enough. The blacks are not very deep, but I didn't get a TV to see black screens. People complain about not seeing 4K. I do get 4K and it looks fine. The source must be in 4K and your internet must be at least 15Mbs otherwise it switches to 1080p.
    3. The sound is fine too. To be honest I always have the TV on low volume. After all I didn't buy it as a stereo.
    4. The Fire TV software needs a little getting used to but that's true for everything.
    5. People complain about little space to store apps. That's true. Personally, I only use antenna and a few streaming apps (YouTube, Twitch, Prime Video). Plenty of space for that. If you want more apps at the same time then you need to use a USB stick.

    The only real problem I encountered was that the TV lost picture 2 times while watching antenna channels. Other people had this problem as well. Interestingly enough, I maintained picture on the streaming apps. The problem went away once I unplugged the TV. That makes me think that it's a software issue rather than a physical problem. I also reduced the back light density to 60% and since then I haven't had the problem again.

    That's my review. I hope it helps.

    2/5/2022 UPDATE:
    I just wanted to add that since I've reduced the back light density from 100% (factory value for whatever reason) to 60% two years ago, I've never had the screen go black again. I'm positive that this is the fix for that specific problem.

    I bought it to use as a monitor for my security cameras. The picture quality is great. I also use the tv when in that room so it works fine for that too. Very low memory and it keep telling me I don't have enough memory left to load an app. I have no idea what app it's trying to load. the remote has no numbers so you can't just pick a channel you have to go thru the guide to find it station by station. That's not a good thing. the remote is very limited in options but works fine for what it's programed to do. Over all it's a good buy for the sound and picture quality but some things could be improved.
