SUPER VERY CLEAN! The keyboard and excellent quality, a bit too light (but I was open and I added weight) It is very beautiful, and fast delivery and trouble, it is compatible with my Mac even if it has key PC / Windows, but for me the only problem is a good idea to put blue buttons but there is nothing engraved on it and just blank blue button. ORMI THIS LITTLE PROBLEM IS PERFECT FOR ITS PRICE, I STRONGLY RECOMMENDS.
