Well, mines be fine.
I think it's only skipped bout 5 times in total, all within the first few hours of using it.
It certainly hasn't skipped for a while (not that i've been riding much though)
Yes, it is stiff, mine even more so as waynio tightened it up for me when he fitted it, but it's not noticeable when you are actually riding it. When i first got it the cranks would spin with no clickage when i pushed the bike along, but now it has got noticeably smoother and it sometime clicks when i push, sometimes not.
The lockring has stayed tight since i got it, i haven't noticed anything wrong with it at all, and i haven't had to touch it once since i got it fitted.
I've porbably just totally jynxed it and it'll blow up in my face next time i go anywhere near it, but, in my opinion it's easily the bext freewheel and just as good as most profile set ups.
You've made a good buy :)
