I recently purchased a new mackbook pro. After shelling out almost 1800(aud) for the baseline model I was quite surprised to find how expensive accessories such as cases and adapters were. I selected this shell purely on price and i was pleasantly surprised. I needed to get the case asap to avoid the mac getting scratched. the case was great, it clipped on pretty easily and in protects the mac quite well. Its been on about 3 weeks now and hasn't come off or become loose.
