The first impression was good, the sleeve fitted well and the price was cheap, but dust and dirt, which is located on the back between the cover and the shell, damaged after a few weeks or months, the lid. (Looks like in small Steinschlaegen). I think the envelope is placed at certain locations to packed, and the dust accumulates at these sites, damaging the shell and the bottom shiny brim. From dust and dirt, as in the description, this shell does not protect. That the back is damaged by a shell, I have never seen in any mobile phone. It should not be hasty to write a review. Have photos to set.
