What I and this unit is particular like the feel. It is simply good in the hand and the thumb is all stress-free accessible. Simply reingesteckt un there you go. Plug and Play works as it should. This is clearly visible the green laser on flat screens, was indeed touted, but since most screens are mirrored, the visibility is only partly (why a star less). Otherwise highly recommended because well packed in the case supplied with it is always ready to hand.
