Suitable as a multimedia keyboard set. Does what it should. Clear that no keyboard with a super tactile get for so little money. But in order to use the video player and the GUI via mouse or einzutuppen a URL in the browser, it was good enough. A novel I would not want it, tap. Range with me about 4 feet until the laptop where the TV hangs. For battery life I can not say much because I have only just under 5 weeks. After use do I disable the always switch on the mouse. + P / L + Windows and Linux compatible (Win7 x64, Ubuntu / Xubuntu 14:04) + Ultra small USB receiver that is always in the socket easily + Keyboard also very compact, so easy to store. + Batteries included + On / Off switch for the mouse - No on / off switch for Keyboard - Tactile keyboard
