Very good but slightly sensitive to scratches.

The shell is relatively discreet and well thought out what I really like. The plastic is crystal clear so you have to make no compromises where color phones. The covers and connections frequently used are easily accessible (eg. Typically to charge via USB or magnetic connector and the headphone jack). The usability is not restricted appreciable. The fit is excellent and the phone is enveloped comfortably in your hand.
A star deduction, there are still, in fact for quite scratch sensitive surface of the shell. Have phone and shell now about 3 weeks in use and a good piece like a raw egg treated (not pushed over surfaces, placed only on clean surfaces), yet are already significant scratches found on the envelope. The plastic part could have been trimmed a bit better, because especially on contact surfaces to phone some sharp ridges were present. Then even my opinion for the price ... But one should really again deduct half a star because scratch-sensitive for a piece of plastic, I find this price is no longer entirely appropriate.
Who do not mind the high price and scratches, which I can still highly recommend this transparent shell as device protection - especially for those who like me have chosen Compact for a colored version of the Z3.
