  • Approved!
Size: 75-inch
while I'm not a TV expert and haven't compared this TV next to an OLED, for what its worth, quality has been great. Everyone at home loved it, streaming favorite series to rewatching favorite movies over again. Initial setup scared me as initial firmware update took much longer than expected, and no update progress was available once download was completed. Only thing that worked was the power button on the remote, restarted the TV, which took me back to update again, this time in less than 10 minutes update was done. Image processing does stay off after turning the TV off or unplugging it, I suppose the latest fw fixed this. Owning a 50" 4-Series FireTV prior to this made app setup fairly quick, logged in to account, all profiles, settings and apps were ready. Internal subwoofer does add a bit of bass but nothing serious, it's just a third speaker, so keep your expectations low. I already had an LG sound bar, so that is covered. Otherwise, sound clarity from TVs internal speakers is great. So good that I turned down all speakers on the soundbar and basically using it as the subwoofers transmitter. Optical output and TV speakers do work at the same time allowing this setup, haven't tried this with eARC. Another minor issue, which might just need a software update is the constant backlight changes while using youtube app. No video has to be playing, as long as YT app is running backlight level changes randomly when less than 4K content is playing. ... show more

  • Love it!
Size: 55-inch
This is a great TV with great picture quality. No need for fire stick as it is built in! No need for cable. Loving it! If it lasts a long time I will be ecstatic! It is replacing a Vizio tv that only lasted a few years. I won’t buy another Vizio. I wanted a Toshiba because I have one that I have had for over 15 years old but of course not up to par with all the new technology but still working fine. I will be ordering another Toshiba fire tv for the living room in the next few days. ... show more

  • This is the one to buy for the home
Size: 65-inch
Ok it has only been a few days but this one is well the best I have seen over all in a very long line of testing tvs the sound is great from cable , antenna , and streaming with no huge noise jump when a commercial comes on . the picture is sharp and clear you can see items in the dark areas where others show a grey or black blur . it looks good on video games tho I do mot play anything better then switch and Xbox on it both look great and good motion where others drop off. I have the 65" and its a keeper now for the best the price was amazing at my time of purchase for this size tv . then add in the plus of the fire tv part lets you add many apps that other tvs block from use and I can't see a down side to it this ones a 5Star AAA in my book . PS tested 23 models before this one! ... show more

  • Picture is Spectacular and Price is Perfect
Size: 75-inch
This TV is freaking amazing. The color is spectacular! We had another smart TV, but apparently we didn't know what we were missing. Everyone who has been to my home and seen it thinks it's just perfect. You can't beat the price. I've seen ones three times as much that didn't look as good. And we were able to pick it up from Best Buy the next day. You can't beat that. Can't wait for football season. ... show more

  • Toshiba fire stick top rating
Size: 65-inch
Received it today through Best Buy. Purchased through amazon and then Best Buy fulfills the order. Of course, I just got it but It Connected easily to my Amazon account, Sirius satellite radio etc. Sound is good, the picture is amazing. I've got multiple tvs and everyone of them cost as much than this or way more. This is the best. i am. not a full connoisseur of TV. There's probably something that's liquid crystal $2000 something or other thats better but this is a steal of a tv. I got the extended warranty for the heck of it.So for the next four years if this thing works I'll be getting my money's worth. ... show more
