Review on 🔒 Waterproof 4 Digit Combination Lock - 2 Pack for School Gym Locker, Sports Locker, Fence, Toolbox, Gate, Case, Hasp Storage (Black) by Puroma by Michael Hemmig

I like the ability to code my own numbers. The combination uses 4 different numbers that are visible on the other side of the lock. Disadvantage - your numbers used to open the lock must be the same to close/block the lock - ie once opened you cannot block the lock again. if your code numbers are not yet set. That means if you don't mix up the numbers every time you open the lock, your code can be visible to others while your lock is open. Of course you can mix up the numbers after you open the lock, but then you will reset them before you lock the lock. I hope that makes sense. In short, I just want you to be able to swap the numbers right after you open the lock and block the lock with the mixed numbers.
