I be use this cover as I write this and it be a great little addition to my Macbook . I be constantly have to vac my key . this keep hair , crumb , whatever from get into it . if you spill coffee onto the keyboard it might give you a few seconds to grab you Mac shake it off and maybe save you 1k . arrive flat , so no curl issue and it be fast shipping . soft , comfortable and I do not find it too bulky and it fit the Macbook , late 2010 model very well . I would buy this again and have think about get a extra , but it be actually pretty tough . I have have this about a month or so , and it be a keeper .
