Keyboard purchased to pilot a raspberry pi used in multimedia station in my living room. The design is impeccable: it's not bigger than a tv remote control while allowing to type text and use the touchpad easily. The keyboard is backlit and is equipped with a battery that recharges via USB. There is a switch to turn the keyboard and prevent its discharge. The battery life is good. The keyboard is also equipped with a laser pointer if you must make presentations. Until then it's prime.
The only flaw comes from the stability of the connection between the keyboard and the dongle supplied. When typing the text it happens that some characters do not appear. Always check that the typed characters are actually arrived on the screen.
