Good investment! 22

The keyboard is very nice and quiet enough (only the "space" key will sound a bit more but I understand that this is the case in many keyboard). Autonomy standpoint, it's very good (several weeks).
Listed mouse, the grip is also nice. 4 programmable buttons and accessible by the thumb (for a right handed mouse), roulette central button supports 2 scrolling modes: continuous or indexed so fast, and can also be "tilted" (left / right) for horizontal movement in a page (eg a web browser). Side autonomy is not as good as for the keyboard and a refill every 3 or 4 days is necessary (use 6-8 hours per day).

Recharging the keyboard and mouse are supplied with a USB cable (1 cable for 2 elements).
No problem to use the elements for a refill.
