I'm on my second one now, and it's lasting as well as the first. I think after my previous post I did use my old one for a bit longer, but the teeth were getting worn. I've been really happy with them, and only this weekend I was reminded how much better they are than other chest jammers when passing a tight and/or wide rebelay when you inevitably get quite a sharp angle of rope as it exits the bottom of the device.
