Broke my second Ottolock, RIP. I think these are a wear item and need a bit more TLC to extend their life.
They did replace the first time and give 50% off coupon the second time so can’t be that sad.
They said they have made a bunch of improvements on the newer model including more reliable innards. My second seems to have died from “Activated Breakaway Button” But interestingly I was still able to yank the ribbon out with the code set despite it clamping down with high pressure.
