I know this has been out for a while now, what has been your experience? I have heard from one local racer that uses one that the chain has dropped a few times and it is a huge PITA to get back on. This scares me a bit, particularly trying to perform this in the middle of a race.

I'm switching to a Middleburn Uno crank if that matters.

If you haven't had good luck with this chain keeper, what did you switch to?
