Friday ordered, was Tuesday in letterbox - the shell is black and feels very smooth and pleasant. Build quality is (as you would for just under 3 incl. Shipping expected) acceptable and okay. The silicone case sits a bit loose, but firm enough. Dirt particles such as crumbs or dust put to it firmly, but once dry, the shell under the tap, using a lint-free cloth and the thing is running like new.
My x10 has fallen recently from my pocket on my laminate floor - thanks to the silicone sleeve of the shock was insulated and the phone is nothing happens. Therefore also suitable for people (like me) who do not want to treat with kid gloves her phone / can. ;)
Through the shell, the device looks a little clunky, but is significantly better in the hand (for my subjective perception, at least).
Anyone looking for a cheap silicone sleeve, can safely access here. Otherwise, I recommend a hard case or a special leather case, who wants to have it processed "good" or better.
