Ok, the price can already guess which one the odd Macke gets delivered. Just is not a top brand. Keyboard is slightly warped, thereby arises when writing an annoying rattling noise, it is not just clean at all four corners. A more stable plastic housing would have been advisable and would not have made the product much more expensive. Why do I keep it? I use my computer so rare (tablet users) and just wanted a small space saving keyboard with Mouse ... and the gamble paid off. My desk looks not so overloaded. The Mouse is ok and makes their service. Easy logon delay detected after booting, but could be due to my computer.
