I've had one for a couple of years and really like it.
However I'm thinking of changing it. I know it's strong (lifetime warranty etc) but I'm just beginning to get a bit worried about mine. I've given them loads of stick including rzine, Megavalanche and loads of crashes in the Peaks. One big one sent the bike tumbling end over end down Stanage Causeway. This last one put various deep scratches in it. As far as I can tell they're all in the cosmetic layer but I just think I'd be happier changing it.
I'd happily change it for another the same though so if you know anyone selling them cheap, please let me know.
