A normal good keyboard as they could get to 20 also, unfortunately, Microsoft had to stuff indeed "think" to drive up the price artificially. Buttons work properly, but the underside is quickly dirty. But this is Microsoft, not blame the supplier who has brought out at the cost of the maximum.
The Andockgefühl is great, to the Swiss keyboard layout, you get used to quickly.
Think about when you buy if you really want the keyboard. If so, this seller is her husband.
