After I got my One V I ordered the official HTC gel skin case for it, the SC S750. Sadly after a couple of months use it has stretched quite a bit already, and slips off the phone easily.
So to replace it I got the official hard skin, HC C750. I had visions of a light metal case - but its just a cheap looking plastic. It fits well, certainly, and does not like it will slip off. But I really was expecting something better quality in both cases from buying the manufacturers own accessory. They charge enough for them, they should err on the side of quality. Nokia accessories were always a bit overpriced but were always great quality and lasted. HTC should maybe take a lesson from them. So I am going back on the hunt for a top quality metal skin for my One V.
