I'm a homeowner who likes to do my own work and this set-up provides needed safety when working on the roof all day. I've found I can tie-off to a standpipe and the rope doesn't slide up the pipe. The brake feature works immediately and you can only move along the rope if you are actively trying to advance the brake through the rope. Like a deadman's switch, it stops movement unless you mean to lengthen or shorten your play. The rope is plenty beefy so I can use it to lean back or grasp it to help walk up a steep pitch. Using it in conjunction w a fall arrest harness. Recommend.
