I waited about a year to review this so I could give full testimony to its durability. First a little background about myself-- I'm a student and use my laptop heavily every day for many hours. I ride my longboard around and my laptop bounces around with wires and all sorts of stuff in my backpack, so I really do put the ultimate beating on this case. For this reason I want to emphasize that most people won't see the wear that I'm seeing on this case after 5 years that I've put on in 1 year.
FIT:
This is a VERY snug fit. If you put the case on as directed, it will never pop off accidentally (ever). On this note consider whether you want to regularly be taking your mac case free. If so this may not be for you since it takes a solid 10 minutes to get the shell off using 2 credit cards. I personally love this though since in the year I've had it I've only taken my case off once because of how non-noticable it is.
BOTTOM PADS:
Here is my quibble with this case, it is minor though. I had the little rubber 'no-slip' feet on the bottom of the case, but after a while rubbing the inside of my backpack they eventually pop out. I ended up just removing them. It slips around a tad, but still less actually than the bare aluminum on your lap. It is a design defect, however, so I'd take half a star.
APPEARANCE:
Beautiful. Much better than the popular 'Speck' cases since it does not have the big brand name 'SPECK' logo on it. I mean come on, I just dropped $1100 on an Apple laptop. I shouldn't have to advertise another company name of which I don't have any knowledge. This was the reason I bought this case initially. For "1-UP'ing" the industry standard, I re-award this case its aforementioned lost half star.
DURABILITY:
Heck I chuck my Air around all the time and its indestructible due to its build quality and un-scratchable/un-dentable due to this case. After 1 abusive year though it has many scratches and gouges (purely my ignorant fault, but hey it happens) so I'm considering replacing it with a shiny new cover, but I guess that means it truly did its job.
5 stars here folks.
