The product came exactly as described, with all functions easy to understand everything even without instructions. Very nice bright colors. The color, the refresh rate, brightness, all adjustable. Unfortunately, a piece of plastic of the battery compartment (the remote control) is me because of my impatience broken (but really insignificant, and without affecting operation). As I said, that was largely due to my impatience or awkwardness. Otherwise, everything is really well. Gladly again.
