I bought the "mumbi X TPU Cases Samsung Ativ S Case transparent black" about 3 months ago. My first impression was good, the cover is robust and stable, it fit well on my Samsung Ativ. Now, after 3 months I took off the jacket and found that everywhere where the shell had contact with the smartphone, have been formed by pressure and dust, scratches and indentations. I always carry my smartphone in your pocket, and I am disappointed by the shell. I say I have my smartphone would be born without this envelope in my pocket does not look it after only 3 months so.
So if you want to protect your phone from optical damage should resort to another product.
