Very easy to use, once the button on the side on position there is more to connect the bluetooth on the Galaxy Tab. The lifespan of the battery is announced 3 months (check) but in any case it is quite reasonable, do not have to charge it every day. It recharges via a microUSB port. The case is high quality, rigid, can be a little heavy for the shot, but it protects my Galaxy Tab so quite safe. Typing is pleasant and the keyboard is perfectly suited to Android system. A product of very good quality so as always with Logitech, however, the price is quite disproportionate to the proposed functions.
