Serves its purpose quite well ...

I bought this keyboard because I wanted once in a while my laptop on the TV in the living room and connect times convenient controlling everything from the sofa. That makes this Taststur / Mouse Combo quite well, and the product can I good friend to ridiculously low price of just 20.

The key touch is bad not to my liking, but in no case. The trackball is not very precise, but if you find the right sensitivity or mouse acceleration enabled, it is fine. The receiver has a decent range, and I had so far not a single time the Sync. Knobs claim. The build quality is solid, except for the rubber feet that were dropped in the box and had to be re-glued.

I would have still required a middle mouse button and a scroll wheel, but it is now not necessary. However, most lack for me is the placement of actually rarely used fn key at the bottom left which actually belongs the strg. button, and the odd placement of the Del key to the left of the arrow keys. These are for me completely senseless and avoidable design errors in this multimedia keyboards of crying out for lack of user testing and leftovers, and are deducting a star.
