I bought an Innocase from BB, and after it scratched my phone, I received a replacement case from Seidio, the "new and improved" version. For a few weeks, the fit was perfect and I was happy with the case, but it also began to loosen and, lo and behold, added my scratches to my case. They are sending me yet another replacement case which I will probably sell -- I am skeptical it will fare any better than the other two.
Credit where credit is due though: It did protect my Evo during a fall, so I suppose the scratches are better than a cracked screen.
Please see the thread about this in the reviews section before you accuse me of spreading "false rumors and untruths." I'm not the only one experiencing this with the replacement cases that were sent out.
As I said, I'd stay away from the Innocases unless you want a case that scratches your phone. If you enjoy seeing scuffs and scratches along the edges, then I highly recommend it.
