Strengths: finishing, excellent. Sturdy padlock. When open, nothing allows a viewer to "see" the combination. Closing in one click, no need to scramble the combination.
Weakness: the combination can not be changed. This is not a real problem, because the only way to know is to observe with a * lot * of attention when it opened!
It works as follows:
The combination consists of three numbers between 0 and 39, for example "5-30-17".
Turn the knob in the direction of clockwise (three laps) to initialize it.
- Stop by the "5"
- Turn the reverse button until "30",
making sure to spend at least once by the "5" (very important).
- Change direction, turn the knob until "17"
- Shoot the lock to open.
Note: When you turn the knob one way or the other, the Nombe of laps you complete does not matter. If you turn "too far" and exceed the number, just continue in the same direction one more lap!
I bought several of these padlocks, which are at an attractive price at Amazon.
