Hard shell of poor quality

Well let's say it clearly, given the price, it does not expect a quality product. But the feel is very soft and pleasant. Shell commissioned for Xperia Z3 purple and demblée received defective product on the right spine improperly. The hull is completely damaged ... so I ordered the same time and in the same package the same version but for Xperia Z2 and I received it in perfect condition and perfectly adapts to the Xperia Z2.

In short, the right edge of the shell is clearly an area of ​​weakness for the Z3 version anyway, probably because of the fineness of mobile and finesse on the right edge (see photo). Forced to cut manually to use this worn casing ... In addition, the corners at the top and bottom of the hull népouse not perfectly the curves of z3 but it tends to be sharp and not rounded which is unpleasant when taking into hand which is not the case of Z2 shell I ordered from the same vendor that it fits perfectly !!!!

In short or a faulty model is clearly a problem of manufacturing and molding of the hull, at least for the Xperia Z3 release.
Buy this shell knowingly. The hull for the Z2 version is conversely without any defect and very good.
