The universal keyboard dust cover is, as the name suggests "universal". You can be good pull on the keyboard and covers all areas. The laterally jutting edges prevent slipping and provide grip on the keyboard. Since I have a slightly different keyboard (G15), this kind of the dust cover is very convenient. The quality and price are right. I am very satisfied and can only recommend anyone who wants a bit has "other" keyboard and in which problems arise in the standard sizes from other manufacturers.
