iFrogz Luxe Case for iPhone 3G, 3G S

I spent a lot of time reading reviews in order to find the most affordable, but supposedly still solid iPhone case. I’m not entirely sure if one exists.
I was extremely frustrated for the first week or so as I could not get the case to snap on and stay on. Only one side would snap it at a time. Then it seemed to loosen up and the case snapped into place. Now I’ll hopefully never take it off.
My last case lasted a year before it cracked. Eager to see how long this one holds up.
I liked this case when I bought it, but I LOVE it now.
Last night, my iPhone slid from its case and fell from the second floor down onto tile in the front hallway. I was sure it was a goner, but nope! The iFrogz case took the hit instead–cracked in two places but protected my iPhone.
I’m back here now buying another couple of these great cases.
