Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Fantastic Color and Clarity

BJMG 9/14/2023

My original plan was to buy the C3 version of the LG OLED TV but they had the two of them at the store right next to each other and you just couldnt beat the color of the G3 version. Since I was planning on wall mounting the TV and adding a sound bar this was by far the best choice. It is amazing and I am still loving this TV. It is very slim and sleek looking while on the wall and the color and clarity could not be better.

We had our TV installed yesterday and binge watched for 4 hours. Its amazing the color clarity and brightness. However be aware we had an issue with the flush Mount bracket. It forces you to install the TV between two studs. Therefore we couldnt install the TV centered on the wall bump out we had built for the TV. We had to use a different bracket to center it and the TV is 2 off the wall. So much for looking like a framed picture.

Awesome picture needs calibrating

AmazedViewer 2/21/2023

I bought this TV and straight out of the box it has a good quality picture. The true blacks are amazing you need low light environment to appreciate it fully. The TV can be better calibrated if you go into settings and I think this is a necessary adjustment.

Great for Gaming

DOCTORMED 2/2/2023

This TV has great quality and the clarity is the best of a TV I have ever had. The size is just right for console or PC gaming using HDMI. I love the smart tv aspect is easy to use and offers all the major apps. The only down side is that about a year after purchase an update came out that removed the use of the hands free function which was a major point of purchase for me. There was also an issue with connecting Bluetooth speakers. I have contacted customer service and was told that this product was one that was made obsolete after the update.

Great artwork

maulepilot1 11/5/2022

The Art Gallery feature of this TV is a bonus. Our LG TV is mounted on our fireplace in the living room. My wife wasnt excited about seeing a blank screen there when we werent watching something. I found the Art Gallery feature and she loves it. I like the Wonders of Nature and Meditation sections of the Art Gallery the best. It would be great to see more images of natural beauty. Mountain scenes are especially beautiful. The national parks would be a great new gallery section. It would nice if you could upload your own images to the Art Gallery but I havent found a way to do that yet.

Unanswered service request

Mkornely 10/26/2022

After 10 months the TV started displaying a vertical line of dead pixels on the screen. A service request was put in months ago and has not been answered by LG does continue to spam me with promotional emails.
