So the purpose of protection is met. However, the quality is not as hoped. The device is quite loose in the envelope. The sewn-in magnet is a little too high, so the screen is locked only when the phone is moved a piece of the shell. Could this be correct, as I cut a approx 0.5cm wide strip of the filling material and have put in the envelope below. This I can now push the Q10 until it stops and the display is locked. For the estimated price I can live with this shortcoming. But therefore only 2 stars.
