I bought the SGP ultrathin plus black iPhone case, within two months of very light use it started to crack at the edges. Eventually, chunks of the stuff fell off. I have sent many emails to the company and have never received a reply. I love the sleek look and it is very comfortable to handle. I am now using the Reveal case and although it is pretty good, the SGP was a lot more comfortable to use. But I don't want to spend another penny at SGP, if they at least acknowledged my emails, I may have considered dealing with them again. Does anyone know of a comparable case to the SGP Ultrathin? Has anyone had luck with SGP's customer service?
