This set of keyboard + mouse is perfect to control my mini-pc multimedia Linux from my couch. The keyboard has a nice touch. The mouse is not afraid of any surface and suitable for almost any purpose (including nervous games at a price of autonomy). The general range is particularly good, especially preserved by the possibility of turning off the mouse when not in use (the keyboard does not need it, it emits only when used). The distance of use compared to the USB stick is quite variable depending on the environment: my mini-PC has USB ports at the back and front; the scope of use is much better when the key is that when the front to the back, while the mini-PC is disposed side (therefore having both the front than the rear over my couch ). I gather that the signal used is easily blurred by the environment (food, HDMI, etc.)
