I have long been looking for a wireless keyboard / mouse combination that satisfies all my (admittedly demanding) requirements. - This product I've found it definitely! - I use the combi now both professionally and personally in the office at home a. - I attach particular importance here to the haptic perception of the equipment. - Both the keyboard and the mouse have fully convinced me here. - The keyboard is designed very ergonomic, the keystroke in my opinion, perfect. - All essential function keys are arranged in place and make sense. - The automatic switching backlight is super. - The mouse is in the size, shape and feel in my opinion, perfectly designed (at least for right-handed, left-handed variant there is to my knowledge, not what may be the only drawback of the combination is). - The radio transmission succeeds flawlessly and easily via a tiny USB receiver. - The battery life of both devices (approximately 1 week at 8 hours usage per day) is quite sufficient for me, especially since both devices can be charged via a standard mini-USB cable and also during charging are fully usable! - In summary: A certainly not very convenient keyboard / mouse combination, but for me really highly recommended!
