My snap on case actually scratched up my phone!! o.0
It left a scratch line around the perimiter of the where the front piece touches the actual phone. Every time I dropped it, as stated above, the case split in 2, so I'd have to chase down 3 pcs on the floor. lol Pretty embarrassing in public. hehe
The case asthetically-wise however, is very sound.
