Familiarity: I've put it through the wringer
I have this on my bike, and suffered multiple chain derailments with the chain wedged between the crank and my now scratched frame. This thing doesn't prevent jack. It might have prevented one or two incidences? I don't know, but I do know this catastrophe still occurred.
