IÕve had this for about a month now and so far itÕs been a great TV. I did have a little trouble getting the picture settings set up how I liked it but once I got that forgives out it was great. The remote acts like a mouse curser on the tv which I did not know when I bought it, but it was a good surprise. The controller is not super complicated, my 3 year old son can work the volume buttons on it not problem. Over all great tv!

After having my TV for about 10 days, I have been blown away of how amazing it has been running! So far it has thrown my old TV out of the park from the new features this TV has. The flow of how smooth everything has been has made me extremely happy and truly recommend this product!
