Okay, mine's been sitting outside my front door for one or two days. 😱
I'm not quite getting the need for the Bump...
It's firm like the Field Case, ever so slightly larger feeling overall -- millimeters, I'd say -- but feels the same generally in hand. Pressing down on the inside of the empty case, I do not feel anything particularly "cushiony" like you get with a CandyShell. (You also won't get the scratches the CS so easily accumulates.)
There is a tiny bit of droop just below the home button, the same as my FC. The buttons might have a scosche more positive feeling to them (volume buttons are improved), the slightly deeper mute button hole speaks to a bit more thickness, and I'd say there's more "lay on the table" screen protection.
I do see more metal around the edge on the right side of the screen... just a sliver, though. That might change over time.
One inconsequential thing is it's quite difficult to get the case out of the inner plastic form that holds it in the box, fwiw.
I don't use glass screen protectors, but the Bump might be friendlier for those if it was a problem with the Field Case.
I'll give the Bump Case a few days to see what other impressions develop. The photos above depict the colors/seize/etc. correctly, imo.
