Be careful to install the drivers and verify that the keyboard is properly recognized for access to touchpad and keyboard configuration functions.
I take a star because the product is sensitive to disturbances generated by the USB ports 3. The scope would be found reduced to 5 m (for me). And it seems that have small problems with the driver (I'm under win8) as a parameter such as the removal of the mouse button with "tap" on the touchpad is not taken properly into account the reboot of the machine. We need to reapply it every time parameters.
Otherwise. Nothing to say, works very well and the on / off switch is very useful to save batteries.
