What I was very important, the keys are up to 2 exceptions (the spacebar and ne other), all just stuck, that is they can be without problems with a flat object raushebeln, clean the keyboard thoroughly, because even in a very clean budget you wonder what all so there is after calming time and put together again. Here you should advance to take a picture, so that you know which key goes where.
However, the weak point is the Unifying receiver. I have the part really lay with the supplied USB cable while extension to the desk and close to the keyboard, otherwise it hooks while writing. So nothing is for someone who wants to put the keyboard on your lap, and thus the PC on the TV will operate.
Otherwise strong buy recommendation. The first 4 years and held the 2nd now NEN since nem half year.
