And I'm glad to have found his little sister for my Galaxy S3 mini!
The shell fits perfectly on the phone is very easy to install (just clipped the inside phone and it holds well) without the phone will bar all the time.
The exterior is rather class and I find that the phone is well protected.
The only drawback is a tendency to deteriorate with time: the upper magnetic clip that pulls, and clip system to attach the phone that ends up breaking.
That said, I want to say that I am particularly violent with my phones, hence my search for a solid hull and cheap! Fall, shock, rapid movements (opening / closing the valve, remove / replace the telephone forcing) etc ...
So for me the value for money is quite reasonable.
