I am very pleased with the keypad facing a one-week test phase in the university and at home. The battery is charged within 3 hours and to keep 3 months, but which of course I can not confirm, according to Logitech. The keyboard is very thin and light (about 180g), yet stable. That's me really most important is that I can just plug in my backpack with other books and blocks I need to make me worry about possible damage without. Also, one does not require a sleeve or bag for the keyboard, which would prevent me from using such a keyboard. So it is of good use in everyday life. The coupling with the Tablet always works immediately and without any problems and what I really like that you can connect both Ipad's and devices with Android. The tactile feedback of the keypad is used to, but after a short time you can thus already working quite fast and good. But I would estimate that people with large hands may have problems with the closely spaced keys could have. The only drawback is the small and poorly accessible ON / OFF slider keyboard.
