Love it!
Amazing item! The picture is beautiful and the thickness is insanely thin. Love this purchase, we bought this for ourselves as our Christmas gift to the house and could not be happier. Without a doubt, this is the nicest item in our home. Also, so happy we bought through Best Buy because not only can we pay it off over 2 years with 0 interest but they also delivered it to our house for free which was so nice to not have to worry about transport. 10/10 would recommend.
