The mouse is okay, fits comfortably in your hand. But she always wanted zickt rum and that is very annoying, because of the range can not lie.
At the keyboard, I can only say, I got the batteries taken out and put them somewhere in a corner. I do not use them. Why? Because it is almost impossible for me to write it. The buttons are so hard, depend in part. A clean or fast typing is close to impossible. And since I write a lot and now times the keyboard is also equipped with ten fingers and not in 2-finger search system simply unusable.
Thus two stars because you can use the mouse or individually.
