So I do not know what some do with their keyboard so that no longer works after a short time, I have this now already since 2009 (commercially bought) and it still does what it should. Yes, the "n" and "l" key is now now blank, which may not necessarily be "likely" in my eyes but not uuuunbedingt a doomsday is, after all, should be able to write as a daily computer user sometime anyway without constantly the to watch keys. All other buttons are not nearly worn out, although so few letters more often than "n" or "L" be used ... xD She has also made no mosquitoes when connecting or otherwise somehow reluctant to work. It is, as some have said, very quietly, which I personally prefer a more than loud Tastengehämmer. It is also suitable for MMORPG games - Of course it is not a Game keyboard but it is sufficient.
The only drawback may well be cleaning - as with any keyboard. In this the keys are on a kind of spring (which is why it is probably so low), which makes it a bit more complicated (in the case that you want the keys and settle all new ranstecken - Friemel work). But can crumb or something you just fine "sweep out" with NEM thin brush.
All in one I can only recommend this keyboard and would by no means be described as "emergency temporary solution". Furthermore, it is also something else on the eyes than ever just everything in standard black.
