OK, just got my new case via a Kickstarter project:
The AL13 Ultrathin Aluminum Bumper! Here's the site:
designed by m ? Blog Archive ? AL13 Ultra-thin Aluminum Bumper
Pros: very thin, feels as close to the naked 5 as I've come across. Looks very cool. Cut-out on bottom is nice and wide and my 5 goes on my ProClip car mount with the built-in Lightning cable attachment just fine--whew! that was my biggest worry! The case also has no problem with my Bodygaurdz "Pure" screen protector and my Zagg shield on the back of the phone.
Cons: I ordered the Black color, but it's a tad off and slightly "gun metal" in finish. Not a deal breaker, but would've liked a darker black.
Also, the aluminum case cuts the signal a bit. My Sprint signal goes down one bar. Haven't had the case but a few hours, so don't know if that's a long-term problem. Will check back if it is.
The cut-outs for buttons are a tad deep compared to some other cases; the volume buttons might get to be a pain if trying to adjust while the phone is in my pocket (I do that a lot while in my gym and on walks outside in colder weather)--this could get to be a pain in the long run--we'll see.
But, like I said, feels and looks fantastic! Will post a follow up if the cons outweigh the pros in down the road.
