ISO layout keyboard & iSkin

My keyboard tends to get very dusty from time to time, and I decided to give iSkin keyboard protector a go. My question is: the Italian keyboard layout I'm using is an ISO one, referring to Knowledge Base; the iSkin site says that their protector works with any "2003 ISO International keyboard layout compatible". The put an image of an American layout for comparison, but the Italian layout is very different in the enter key zone, as well as any other European layout keyboards. Does anyone of you tried this keyboard protector with any European keyboard?
Thanks for your help. Bye bye.
