    5.0 out of 5 stars Good TV good picture I just recommend getting a soundbar and a stand or wall mount separate
    Reviewed in the United States on June 22, 2020
    This is a very good TV if you're on a budget and you want to get something decent for your man cave although the sound is not great that these things put out that's not really what you buy a modern TV for and its more for the picture if you are going to buy a flat panel I would highly recommend a soundbar to go along with it for better experience my dad has the same TCL and the sound is underwhelming two say the least
    But that's not what you buy a flat panel for since most of the sound quality on flat panels has gone down nowadays but if you do by this I would recommend getting a JBL soundbar to go along with it and if you do buy it I would recommend getting a table top or a wall mount TV stand if you have a skinny entertainment center the TV legs are not going to do you any good I kind of wish it had a pedestal mount but if you want to have it on your skinny entertainment center and you want to go big you're going to need a tabletop TV stand to go with it and I'd highly recommend getting a JBL soundbar or any other kind of Soundbar that's ranked I don't recommend just using TV speakers you're not going to get the full home theater experience if you just use the TV speakers other than that though the TV is a nice bang for the buck besides having to buy a separate TV stand I really wish they would go back to the old pedestal mounts though instead of the unsturdy TV feet I wouldn't trust those things with my life for my TV if you're going to get one I recommend a wall mount or a flat pedestal stand to buy and mounting it whether you manage to the wall or on a pedestal stand is up to you but you can easily find a much more sturdy pedestal stand on Amazon for less than thirty bucks and it's made out of metal and will last unlike the flimsy TV feet which I do not trust which is why I wish they would go back to the old school pedestal mounts they were much sturdier and could hold up a lot more weight I didn't even bother with the TV feet when I got mine the picture quality so far has been great like I said I just wish they would go back to the old pedestal mount for every TV manufacturer this doesn't just go for TCL to me it stinks that you have to buy a separate stand if you want a pedestal Mount nowadays but to be honest I would just get that even if you have a wide entertainment center I would not trust those flimsy TV feed at all TV feet aren't really that great in my opinion if you're going to get a tempered glass TV mount but the picture quality is great it is worth the money you pay for it I'm just saying it would be best to get a separate TV stand if you're going to buy a $230 TV so make sure you protect your investment and get a good stand and do not trust those flimsy TV feet

    Great tv for the price! I bought this tv on a whim. Didnt need one but couldnt pass up the price. The tv is lightweight and easy to set up. Just plug it in and you're ready to go once you set up your roku account if needed.

    My tv however was sent to me with a missing remote for the tv itself but it's not needed for streaming anything. I called Amazon and they are sending a replacement remote which is totally fine in my book.

    So if you're looking for a great tv with a great price this may be your ticket!

    5.0 out of 5 stars GREAT TV! Didn’t come cracked
    Reviewed in the United States on June 23, 2020
    I was really scared of getting this off of Amazon because who gets a damn tv from online, but I’m glad I did. It saved me tons of money. I was skeptical buy because I did notice from the reviews that the tv will come cracked sometimes, but mines didn’t and works perfectly fine. If you know the amazon workers in you area throw the stuff or isn’t gentle with it don’t buy. It’s not the products fault it’s the amazon workers who place it or work in the warehouse.

    Sound quality could be better. Haven’t been able to set up my cable remote yet. Wish it had a swivel rather than the two stationary legs. But overall good tv for the price.

    The TV came quicker than expected which was an added bonus on top of the other pros. Really easy to set up and use and the smartphone app remote is great if you don't feel like grabbing the remote. The picture quality is stunning and there are a lot of ways to customize your preferred viewing. The remote is nice though, as it has shortcut buttons on it that can bring you directly to Netflix, Hulu, and ESPN,

    1.0 out of 5 stars Invest in a better TV. This one is not worth it.
    Reviewed in the United States on October 29, 2020
    So I never write reviews. This is actually my very first review after being an active Amazon user for over 4 years now. I’ve usually been very happy with my Amazon purchases but this one was such a horrible purchase that it inspired me to write this review.

    TL; DR... This TV broke in 4 months.

    At first I thought it was the remote or the WiFi but after days of troubleshooting realized it was the TV hardware that was messed up. I’m very disappointed and even more disappointed that I cannot return this because it’s been more than 90 days since I ordered it.

    If you are going to invest in a TV, pay a little more for a good brand. I heard Samsung is good, and there are other brands that might be a little more expensive but better overall. This seemed like a product that would save me money, but it ended up causing more pain than anything. I won’t recommend this product to anyone.

    I have bought one on Walmart and came smashed. So I decided buy on Amazon and the fast shipping and the care putting the TV in an extra cardboard box made a huge difference.

    The TV colours are very bright and beautiful. The Roku system is very quick and efficient, it's easy to download apps like YouTube, netflix , change themes. Couldn't be happier. Excellent TV with an amazing price.
