Scuba Diving Retractor Lanyard with lock

Initial review below. After only 4 dives, one of these (used for torch, dive stick & GoPro) has lost its plastic coating and jams up in retraction......They were quite a big bigger than I had expected but fit into the bcd ok. Retractors work well although occasionally, (ironically because of the 360 degree swivel feature) the lock/unlock button can easily be pushed against the bcd. Only happened a couple of times over 4 dives this week.
