Nickel, the best I've found and tried.

Purchased black.
I had already bought a case for my mini S3. My daughter also another model.
Mine: the leather was of very poor quality, but the hull was good.
My daughter was the opposite: the purple leather remained like new but the shell fell to pieces really.

THEREOF:

It links the qualities of 2 previously purchased:
A shell that holds up well gsm and is solid (not broken after 2 or 3 months)
AND
A high quality leather exterior. (It still looks new!)
No problem for headphones but that's all right!
The practical hole for loading leaving closed (I was not on the previous)
The magnet very firm (neither too strong nor too weak) and closing on the bottom no longer bothers me to phone (unlike the former who came on my ear). Opens easily with one hand and closes easily.

In short, I searched long to find this rare item.
