The shell is harder than expected, silicone cases we have always had only considerably softer.
The fit is not 100% accurate and so it was a little difficult at first, the mobile phone the shell "to attract".
We have then only one time placed on the heating and then used.
After a week of use, there is still nothing to complain about.
From unpleasant odors I can not talk.
Overall, extremely satisfied, as measured by the price.
