Rated 5 out of 5 by from Fantastic picture quality I purchased this about a month ago to replace my Sharp 42 inch model and have been blown away by the quality and features of it. The different sound and picture modes are a real game changer for me. By being able to choose the sound and picture qualities that suit what I'm watching makes everything so much more real and enjoyable. From being able to surf the net, access netflix, Prime video, Alexa and all the other apps to the LG channels, which are a great break from the cable reruns, this is by far a great TV.

Rated 1 out of 5 by from Worst customer service experience! Bought this TV a little over a year ago and paid a lot of money for it just to experience burn in and now customer service says that the warranty period has expired and they will not fix tv. Worst customer service experience ever! Hopefully I win the sweepstakes from this review so at least I can afford to buy a TV from there competition and have a better experience at this point.
