I have one for my 8330. I Love it. It makes the phone a little bigger but I have big hands and I it helps me hold on to it, not to mention the protection it provides.
I have it for my 8310 and love it. It's durable, easy to hold, and Otterbox's customer service is excellent. My first Otterbox didn't fit just right, so they sent me another one and didn't even ask for the old one back. They're awesome.
