I bought one of these when I first got my now ageing phone. It lasted best part of 4 years but started to get shabby. I therefore bought a new one from Mobile Fun. This new one seemed flimsier. It actually only lasted about 4 months before it fell to pieces.
As the cases are quite cheap I have now bought a 3rd one.
Let's see how this one lasts. At least this one seems to be assembled correctly with the patterned covering material applied squarely to rest of case.
