First I want to evaluate the product. The sleeve fits comfortably in your hand and is easy to grip on the sides. The cut-outs are punched very exactly. Now for the negative. The delivery time was far too long in my opinion, despite the class of payment on my part (debit permission) passed over a week. That's a No. If the quality of the shell is not good, I would have gone on all roofs. Nevertheless, I'm going to order anything with this provider.
