On the first attempt to insert my Z2 slipped it out in no time again. Thereupon, I bent the plastic clips gently inwards and have since no more problems. Actually, I expected that, as with other FlipCases scuffs arise after a certain period of use, but even after two months is nothing to see on my smartphone. This is of course very gratifying if you want to sell it once. So recommended in any case. With the time I have the Flipcase been 5 months since I'm not the power user, it still looks very good. Some crashes survived my smartphone thereby. It will certainly hold out until I order the next mobile phone.
