I bought this as a motorcycle helmet lock, for which it works great except the lock itself is is totally cheap. I don't even care so much about the level of security, as this is just a deterrent so somebody can't easily walk off with my helmet; but locking it and unlocking it takes forever. To unlock, when you turn the key it doesn't just release or even disengage so you can pull the pin out, you have to wiggle the key to get it to disengage, and at the same time wiggle the pin while tugging. Then to lock it, it's just as difficult. You don't need the key, but the pin doesn't fit well and has to be wiggled and forced. Like I mentioned, this type of lock with this length of cable is perfect to use as a motorcycle helmet lock,but I would shop around for one with a better lock. The only thing I would add is both the lock and cable are wrapped in a rubber casing and shouldn't scratch your motorcycle, which is why I chose this model. However, for $5 you get what you pay for.
