minimum price for mimimums functions

Should not expect a product of very high quality for this price. The distance is to use no more than 2.3m. The sensitivity of the mouse function is not really practical and no drivers to customize the buttons. Still, it works and feel of the buttons is nice. If you are looking for a cheap remote control to troubleshoot this is the product for you, but if you want something more specific, more convenient and customizable chosen a product of the upper range (with logitech for instance)
