Fast shipping poor quality product

Ordered on Sunday, comes Wednesday! 3 business days only.
Product purchased to protect my brand new Macbook Air, but the label on the packaging Announces shell for Mac Pro /
However I feel they only sell one product compatible for all models (with similar dimensions, certainly).
Indeed, I managed to place the hull, but only after a few minutes of struggling (as others, I thought that the hull was too small).
However placed Hull and still in place after 24 hours of use. While attached, the job done. True color. Material very pleasant to the touch although rather messy. Supplied with a protective cover. Good value for money!

Update 02/01/15: ATTENTION, after a few weeks of use, the front part of the hull has been removed, it is also a little cracked. I will not amuse myself back into place every week. I do not recommend the product.
