Review: Good locks - I’m happy they work
Review: 2 identical keys for 4 basic locks - Simple and basic padlocks I needed to lock some outside sheds. The sheds aren't built with the best security so I needed a padlock that was OK but I didn't want to have lots of keys. These were good value and should do the job. They are only to deter an opportunist rather than a determined attack.

### ⭐⭐⭐⭐⭐ Good locks

I’m happy they work

### ⭐⭐⭐⭐ 2 identical keys for 4 basic locks
*by P***S on 20 October 2022*

Simple and basic padlocks I needed to lock some outside sheds. The sheds aren't built with the best security so I needed a padlock that was OK but I didn't want to have lots of keys. These were good value and should do the job. They are only to deter an opportunist rather than a determined attack.

### ⭐⭐⭐ Not suitable for outdoor use
*by C***Y on 25 February 2024*

Used these to lock bin chains. Started to become hard to use after 9 months. Fully seized closed in less than a year. I oiled these several times and even that didn't help.
