Silicone Case good leather flip cover bad

What really surprised me was that the silicone case not to halogenated organic compounds etc. (just plastic) smells.
You can attach well, keeps well and seems well when falling well protected (phone has once again sought contact with the ground).
Have (because so cheap) bought in pink, purple and green, this silicone case.
Conclusion: This good rating refers to the silicone cases in Pink, Lilla, Green.

The black flip cover, which I have just received the case with the same delivery, smells at the beginning.
Although it goes well but the phone can be removed again without much effort (possibly too loose ?, could avenge the fall), the processing is relatively poor (scratching seams and the whole thing is a little crooked) and the magnet does not hold very Good.
Because I have experienced at other manufacturers better (but was also a bit more expensive).
Conclusion: The flip cover is only 2 star value and next time I will not buy this cover, but a little more expensive, which is more workable.
