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 and 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.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Absolutely stellar TV with amazingly bright pictur

Submitted by Chain - 9/22/2017

When I bought this TV it was the beginning of upgrading my home entertainment system to 4K and I originally bought it by price and manufacturer name and reputation and I have yet to regret my decision. It has an amazingly clear bright and crisp picture along with more apps and features than I will ever use for my simple needs. After attaching it to my Xbox One S I immediately noticed a difference from my old 1080 TV and now that I can purchase and watch digital movies in true 4k I will never go back to 1080. The sound picture and quality are amazing and I have recommended this to all my friends who are upgrading to 4K.

Fantastic unit

Submitted by Mediamon - 2/6/2016

Picked this thing up last night as a second TV to a 60 DLP. Its primary use will be gaming. We looked at a wall of TVs and drew straight to this one. The picture is friggin amazing Run in test was a couple of HD movies and holy cow Tempted to make it our main TV if not for the smaller size. Then hooked it up to the XBox... Unreal Nothing about it is not to love. WiFi Image cast Screen mirror remote functionality. All of it is flawless. If youre in the the market for a 50 class and thinking about this one then have no fear. Youll love it
