I use the computer at home. Since you have ever an apple or a sausage sandwich in hand while surfing. This results in even the warmest mindfulness to verschmalzen the keyboard. A PC keyboard you throw away then ever, if it is dirty. Each keyboard is inevitably dirty sooner or later. The Silikondeckchen fits, of course, it taps not be as good as without, but it has quickly become accustomed. I am writing 10 fingers blind and am after a few thousand strokes again about the same rate as before. The cover is so heavy that it slips when fast not just write from the keyboard, but is so thin that it remains gefühlsecht (you can see the bumps on the F and J still palpate). I find the price a bit steep, 5 would be more appropriate for a napped Gummideckchen, unfortunately the product is no alternative. Therefore, you have to pay just 12. But already you get the way a PC keyboard. The course is easier to manufacture than a silicon cover ... So a bad comparison. Naja is only money. It prevents up to 12 that the 80 Mac keyboard is disgusting after one year and after 2 years is broken. Glad toothpaste no 50 costs.
