It is not very strong but I think is good enough for my gym locker. It is not a safety lock, parts are in plastic. Nice design and it is easy to change the code. Very small.
The lock is good. didn't try it yet on my locker at the gym. When it opens there is half the space available-see 2nd picture. Easy at changing the lock combination, first put the correct combination to change it. I hope it will be at good quality. In general it looks good. I got it fast.
