The workmanship is good. For leather shoes, I might have criticized the seam at 2 or 3 bites, but for a cell phone pocket in this price range that really is fine.
The shell is so stable that it is sometimes not noticed ringing and vibration in the host bag, which must be a clear.
Unclear to me was when buying the "return function":
This is a flap with which one can draw the cell phone a few centimeters out of the casing, without fumbling, which is quite handy.
Only I would have specifically as Xperia Pro, which has a loop fastening, just wished that the envelope hereby works to prevent that one drops the envelope when making calls from his hand.
All in all, well worth the price.
