Rather than silicone, I would have used the word plastic to define the terms of this cover. It seems a rigid hair to effectively protect my Galaxy S. Fortunately, the drop test has not been performed then will we say that the device protection has not been tested. Last remark on the cover include expanding the cutter opening for power plug the micro USB socket at the bottom. However, we must still say that my Galaxy S is still beautiful with this cover. For cons, the screen film is impeccable. I said that it was matte, which reduces somewhat the image quality but at protection, nothing to say, this is perfect. When I see that there has scratches on it after just one month of use, I'm delighted for my screen, these stripes places no discomfort for handling the device.
