  • Solid for a 4k
    Reviewed by shaggy9869 - May 11, 2021

    [This review was collected as part of a promotion.] I received my 65” after unboxing which was pretty easy to do, setup was easy. Connection options not working have been an issue with this TV. Not a huge deal but one downside I’ve seen. The option to pick a smart assistant to work with your smart home is very nice. Additionally selection of apps is sufficient, with Apple TV included and Airplay ability makes for a well rounded device. Overall I’d say I’m satisfied wit it. The solar powered remote was a nice added feature I wasn’t expecting. Picture quality is great as well.

  • Love my 55” Samsung Q70A !!
    Verified BuyerReviewed by XBoxSX - April 23, 2022

    This Q70A 55” has super sharp screen resolution. I game a lot and the TV automatically goes into game mode for input latency. The TV is so light and very thin for such a large screen. The border around the edges is almost unnoticeable. Samsung Plus is free with the TV and offers alot of viewing channels. A ton of APPS to choose from as well. This TV is an excellent buy !!

  • Steer Clear If You Want Consistent Blacks
    Reviewed by newfromblammo - April 30, 2022

    I would not recommend this TV if you want consistent blacks with no clouding. The middle-left of the panel is far less than acceptable, and had I known in advance I would have gladly paid hundreds more to purchase an OLED from another manufacturer. Other users have reported the same issue. r/SamsungBuyerBeware
