The shell looks at first glance really classy. The impression is deceptive, however, the part is made of very light plastic, just the reverse is blinded in my opinion, only with aluminum. The first time you take off and that was not gross motor, both corners have been broken. Too bad after all, it is declared as a cover aluminum, metal Bumper what is not the case! The seller claims that the customer's improper handling! Zero insight, no exchange. Sell scrap and then threatened with a display if you do not delete the review!
