Review: Does the job well - A very good and strong padlock
Review: Easy to set the new combination, very secure design. - These are the best value padlocks I have found. They're so solid, I bought them for the garden sheds to replace the key ones since multiple people in the house use them. Being able to set the combination is a handy feature, I could set them to something all the users can remember. I think you would need a grinder or something to hack off that lock because the design is too secure for an opportunist. It's only been in use for a few months now and there is no sign of rust or weathering, I'll update the review if that changes, but so far it's weatherproof.

### ⭐⭐⭐⭐ Good lock. Incorrect combination number.
*by A***N on 25 May 2022*

Padlock is sturdy and exactly the size I needed. However, I was unable to open the lock with the factory issued combination number given. Managed to unlock it eventually, actual combination was 10 digits out!
