But I was puzzled :)

Until now, I had a key protection for my iMac with printing molded keys on the keyboard volume model. It was perfect. It is no longer available and apparently the Macbook protection are not compatible with certainty. I dreaded this silicone protection Yet it is thinner than the last while having good strength. It poses no problem and does not move. One of the two surface is "adherent" than the other. Readability is impeccable, well above what I had. Velvety touch. And I'm reading other reviews, for me it is absolutely not hinder the keypresses. It's almost invisible, unobtrusive and much more convenient than my old protection molded on keyboard. I'll buy another for my laptop. The resistance seems very good and apparently produced little wash. Absolutely no complaints
