Received it a few days ago, I found that the product is not necessarily well designed. Indeed, the flap with magnet is positioned over the part at the back, so that you always have something that bothers you the ear when you call.
Moreover, from the perspective of the finish, there are traces of glue everywhere, a gap between the shell and the back flap, scratches in the inner shell, and even fingerprints.
In short, helpful, but I probably should have received the first copies of a product for which the production process does not yet appear prowled.
If the pen does what we ask.
ps I have not yet tested the shields.
