1 / the shell is not completely "opaque" so that if you put your black iphone, all give the impression of gray or dirty white. It's bad enough as rendered if you want a pretty bright white.
2 / this protection does not feel good and smell stays on my hands after taking the phone 10 minutes for example. It is very unpleasant
3 / The design of the back of the shell actually pretty cheap. Kind of unsightly circles ...
4 / This shell is less anti-slip another Amazon hull but I already black ...
It's just incomprehensible. Besides, one I did not in the Black all these anomalies and a much sober design. This is the reference "AmazonBasics - Silicone Case + Screen Protector for iPhone 4"
