I bought the keyboard to surf on the sofa with an Android Media Station ... to. The keyboard is the format cute. The trackball, however, is a disaster: The fit in the guide is insufficient, so the ball likes to lose contact with the Abnahmern. Result: one round and round: alone nothing happens on the Bilschrirm. The mouse pointer appears that stuck to make then the wildest leaps.
The whole thing has been tried on 2 Netbooks: with the same result.
