I have had several of Seidio's products and while they do offer good protection while remaining extremely slim they do have one major flaw. The surface cases allow dirt and dust to get behind the case and it collects in the corners of the case. Over time this dirt and dust will dig into the phone and cause what looks like pitting around all the edges and especially the corners. I have had this problem on 3 different phones (Blackberry Storm, HTC Incredible, and HTC Thunderbolt). This is why I have opted for the OB commuter as it offers a soft case around the phone and protective hard shell around that. The other problem with the Seidio convert and active is that the corners are the ABS plastic instead of the TPU material for shock absorption.
