For the money spent on this particular helmet lock, it's okay. The downside is that the outer shell as well as the combination rings are plastic, and I don't know if the rings in particular will withstand the test of time. Easy combination setting, but I'm not sure how secure it is. Of course, if someone intends to steal the helmet with a cutter, they will succeed very easily because the cable is thin. I think its use is exclusively for a very specific purpose, such as holding the helmet and preventing theft by random people.
