I drop the cash on this expect just a average product , or just a cheap knockoff of the much more fancy $ 30 cover from the iSkin website . I be pleasantly surprise when I open the package and stick it on , and find that it just happen to be pretty dang snazzy . it look good , feel good , and fit really well . the key line up perfectly , none of that awkward double character effect . the backlighting be subdue a lot , but not so much that it be render useless or anything . as far as typing go , it feel natural . it take about 2 minute to get use to it , then the `` this be weird '' effect wear off . not to mention , this cover just make any typing SO SO comfortable ! the post do say high grade silicone , and they deliver on that ! overall : Worth the money , but I would caution buyer about the packaging when ship . seriously ? a envelope ? I pay $ 4.95 to have this ship , and it come to I in a old brown envelope . the product be fine , but there be much that could have go wrong . beyond that however , I highly recommend this product , it will extend the life of you mac at least 5 fold .
