I tried ozaki 0.3, ozaki 0.5, thinedge bumper, tpu bumper and Zero 5. First of all bumpers dont suit iPhone's 5 design... they were good on the shorter/bulkier iPhone 4 but in iPhone 5 i think they destroy its unique design. Thinedge bumper is slim but the grip is awful. Ozaki 0.5 has a hard plastic feeling like Zero 5, gets scratched easily and its not too slim for my taste. Best case of them all is ozaki 0.3... great soft feeling and the frost effect adds style... But i am looking for a 0.3 Clear case.... has anyone found anything yet...if it is Jelly even better?
