Great value for a 4K product
Partly because I had previously purchased a Sceptre Naga monitor and had very good service from it, and partly because our local TigerDirect store was closing, I purchased this U508CV-UMK model. I selected it over some others, including "smart" TV models in part because I did not want to buy a "smart" TV that in a couple of years would be outdated. For a better price, I got a 4K TV to which I can add my own "smart" devices, such as a Roku 3 box. If I want, I can connect a computer as well, as I did for a test.
I am very pleased with this purchase.
