No, not yet.
I have been through 6 cases so far, and not yet...
My first case was this leather belt clip, no name company in canada, lol it was really good but it just was sometimes uncomfortable and not very stylish...
Then my second case was this belkin designed silicon case, not very much protection and loose as hell...that was crap, my third case was my closest to 'the case' it was from the same company who made the belt clip i mentioned, it had great protection, but on the right side of the case it kept clicking when i held it, and it was cause i dropped it and it screwed it up....my fourth case was the switcheasy devil capsule rebel, great case, my fave to date back then, only problems, left high side is a bit saggy, and the bottom is saggy, and back scratches a ton....and looks like **** cuz of that, so i got the switcheasy colors, in purple, pretty good, decent protection, a lil loose on the sides...but it ripped and so yesterday i bought the capsule neo and it is GREAT except for 2 things: the I-frame wiggles a **** load, and the 2 condoms that came with it ripped a bit....that last part doesnt really matter tho...and my reseller wont swap it for me....i plan on buying the black neo and mix up the colors, have the condoms black with the clear plastic and the black I-frame. and sometimes with a white condom and the dark translucent plastic and the white I-frame...but I have heard they fixed the wiggle recently, i guess mine was an old case, so the capsule neo white is THE CASE! (if you dont rip the condom)
