IÕm so impressed that I donÕt have to keep adjusting the volume anymore because I can understand what is being said. The sound clarity is amazing. ItÕs too soon to review the full smart technology as we just moved here and other projects take our time. Besides, IÕm on the old school side and itÕs a little intimidating but IÕm determined to do it!

My wife bought me this TV while I was on a business trip and I was happy to see how fast the processor was compared to the old set we had. The apps are really easy to access and the setup was a breeze. Crystal clear picture and decent sound without a soundbar upgrade.

Good overall

IÕve had the TV for about 3 weeks now and I think it is a very good tv. Quality when the camera is zoomed in on something is very good. However I feel like when it is zoomed out like while IÕve been watching the World Cup on HD channels it seems somewhat blurry which is dissapoinging. I do know that the TV is capable of 4K while streaming and Netflix looks great, just dissapoinging that cable canÕt look as nice as well.

Great TV

I researched several TV's and I found this to have everything I wanted and appeared to have the best picture also. It has proven to be everything I wanted and I am very happy with it.
