Great dependable tv.

This is our third LG TV purchase this year and we're very happy with both 65” and the 55”. When it is back in stock, we'll order a 27” for the kitchen. They are easy to navigate and work very well.

Hello! We’re excited to hear how much you’re enjoying your LG TVs. Picking up the 65" and 55" in the same year is quite the upgrade streak, and it’s great knowing they’ve been easy to navigate and performing just the way you hoped. We love that you’re already planning to add the 27" to your kitchen lineup once it’s back in stock — sounds like an LG home in the making!
