Customer Review of Agent18 Eco Shield Case for iPhone 1G (Black) by Jordan Bonitatis
Customer Rating 4 of 5
Customer Summary Probably the best, but not flawless
Customer Full Review This is a great case. It's protective. It doesn't add bulk. And its smooth plastic rather than rubber so it doesn't pull out your pocket liner ever time you grab the phone. And it won't stretch like many rubber cases.

The only issue is that its not a PERFECT fit. Its very, very close, but there is a tiny bit of jiggle room. I would love if it snapped together a bit tighter, but, like the headline says, its probably the best out there.
