### ⭐⭐⭐⭐ Locking action could be better.
*by G***T on 18 March 2023*

Although reasonable value for the price I find this lock has a very vague locking action that doesn't inspire too much confidence, and it feels like it would take too much levering to force it open. Edit: After a few months out in the weather this lock seems to be holding up well, so I'll treat it to another star...
