About the quality and workmanship you really can not say anything, very fit and the whole quality. The design I like very much. Unfortunately, there are 2 points of criticism: - Mostly the battery cover when take them from the shell dissolves with, because the material is somewhat rigid and inflexible. - And the larger point of criticism: The battery charge is limited. The charger plug can no longer fully be infected, because the shell abuts the plastic part of the connector. It works, but with smaller movements the cable drops out again. Laden is so only when the phone is quiet on the table or the sheath is removed (in which case just the battery cover with triggers.)
