Logitech no introduction but again this is a good product that would still be possible to improve. Goodies: good battery life (to a condition, see the least :)), good range of Bluetooth (a condition see even less :)) really compact ergonomic keyboard and generally satisfactory. Cons: to conserve the batteries have to think long to switch the on / off button (automatic extinction would have been a plus), the Bluetooth transmitter carries much further if we add a USB extension cable, and the buttons on the touch surface are a bit too big and ask to make efforts to move from right to left click click.
