What people are saying

Rated 4 out of 5 by from Good Basic Smart TV I bought it on sale for the price. It is a great TV, with the exception of the apps available and the upgrades on the firmware.

Rated 5 out of 5 by from Awesome! After waiting several years to even have a LG SMART TV, I finally received not one but two for Christmas! Imagine my surprise! Absolutely love both TV's, one in the Family Room and the other in My Bedroom. I am a lucky person to have such a wonderful family and friends - I was always saying I would be the last one to get a SMART TV, no I have 5 of them:) Love it!
