Generally, as a case, it is very good. 3 stars because it does not charge the pen, the case needs to be removed to charge magnetically.

Update

It actually charges the pen, sometimes it just doesn't detect it. However, if it is simply placed on the case, it will eventually charge, there hasn't been a time yet when it wasn't charged.

I have Spigen cases on all my Apple devices. I think it's the way to go if you want something of quality and not at the prices of the authentic Apple cases.
