I was looking for a decent case system for my Macbook Air. It fits very well and even comes with a keyboard case (anyone with kids will appreciate it). It looks simple (no fancy case design) but I'm happy with it for the price. Shelf life information will be updated in a few months. TO UPDATE. This went on for about six months before one of the corners cracked and broke off. I ended up ordering the KEC sleeve that we have used for all of our other MacBooks (KEC sleeves seem to be much more durable/last much longer).
