Granted ... 1

I was referring primarily to the mouse (I've already 2 thereof) of which I am convinced that it is one of the best ever. With the battery life I am completely satisfied, a charge is amply sufficient for 5 days and where the problem is to hang them at night to the computer to charge ?!
The backlighting of the keyboard was a nice surprise (I had in the description completely read) but I find it quite fittingly and especially in the evening helpful and using indirect illumination. The keys are a little too flat for my taste and the feedback via clicking sound I miss a little, but is simply a matter of getting used. I also have a delay after switching found that sometimes occurs in the keyboard. Here, from and "swallowed" at the first keystroke then.

Otherwise, I am very satisfied and would recommend the set.
