This shell fits closest to the Mac. The installation is easy. It will protect the best impact. I especially liked the little rubber on the underside, which provides good stability. The ports are well accessible thanks to well studied notches. The material is pleasant to the touch, polycarbonate, with a 25 year manufacturer warranty anyway. And is provided with a scratch-resistant coating. The closing is secure and will not open unexpectedly.
I removed one star for the price first, even if the quality is paid! And another for the weight it adds to the Mac. For sure you can not have everything. With this shell, you'll at least a protection worthy of the name!
