It does the basic job of securing your cycle when you need to lock it someplace. However, I am not sure how strong it is. Should be fine for locking the cycle during the day when you are moving around, but I am not sure if I would trust this to locking my cycle for the night.
2 issues I have
- The numbers on the dial for the lock combination are just 1 to 6 (as opposed to the usual 0 - 9). That still gives you potentially over 4000 combinations
- the combination is a preset combination. You cannot change it to what you want.
That said, handy if you want to lock without bothering about keys.
