I have had my black matte Incase Slider for about 5 months now. I bring it to the gym, I travel with it, I kick it around the block with the kids... no I really don't do that.
But yeah, this thing is flawless, there isn't even a scratch on it let alone peeling paint. I am amazed at the fact that there isn't a scratch, most cases scratch the same day you put them on.
It was a problem at first with them because I did have one that peeled way back in July or so when the phone came out, but they changed something because this baby is flawless.
