i am a little disappointed in this lock. Out of the box the line pulled out and coiled back no problem. Out in real life, however, it is a real struggle to get it to coil, and i sometimes end up having to just shove it all in my pocket which obviously kind of a pain. other than that it's fine. i don't know if this is a defect or just mine. However, i bought one for my gf too and it doesn't seem to have this problem.
