The padlock is fine.
Because someone might have trouble opening it since the instructions are not clear, I will write them a little more detailed.

Let's say the code is 17 40 34.

1. We turn it clockwise until 0 (like the hands of a clock).
We make 3 counterclockwise rotations and end up back at 0.
We continue clockwise until 17.

2. We turn it counterclockwise, make a full rotation, and reach 17, pass it and go to 40.

3. We turn it clockwise to 34.

We unlock it.

CAUTION
It is not the model that can be unlocked with the key from the back. At least that's not what I received.

It is a little smaller than what it says, it is a little difficult at first until you learn how it works, but the combination is unmatched, it is good for closed spaces like a gym.

Very good, sturdy, and if you learn it, easy to use and very safe. It is impossible for someone to find the combination like in the others, as it has three numbers that one has to find in the correct order and with the correct turns, practically impossible.

Very difficult to use even after many attempts to learn it!!!
It is frustrating and the password cannot be changed, I do not recommend it! And it is non-refundable!

The best by far compared to similar products in this category. Tank vs kettlebells. Just be aware that it is a bit thicker and if you want to use it for a cabinet (e.g. gym), it may not fit in some.

Very good for its price. It works correctly and accurately in rotations, at least until now.
