Let's be honest. I had already bought this product there are 6 months. A product for mini one m had been sent by mistake instead of to m8. Unable to return it because the seller m sent a return card without barcode not accepted by mail. I put a month to get a refund. Not wanting to stay on a failure, again I purchased the product. And as I finally got the version for m8, tt is well, even if suitable product of average quality.
