Drains battery
I got one from Fentek Industries and the keyboard drain the battery so fast. I have to change the batteries every few months or less.

Sticky Mouse
The mouse on the keyboard does not roll smoothly. It is sticky and there is no way to remove the ball and clean it. All in all it was not comfortable to use the mouse because you needed to use both thumbs to make the cursor move where it was needed. I normally use a trackball mouse but this one just didn't feel good.

Don't buy. Trackball doesn't work well.
It is a poorly made keyboard. Don't buy it. The keys don't work very well and the integrated trackball doesn't work very well. Also there is no stand adjustment on the keyboard bottom.
