### ⭐⭐⭐⭐⭐ A really useful item!
*by C***M on 29 August 2025*

Sticks well inside the key box and stops the key being removed!

### ⭐⭐⭐⭐⭐ Good bit of kit
*by P***L on 10 August 2025*

Good bit of kit. Well used as a key tether and seems to be holding up well. Time will tell.

### ⭐⭐⭐⭐ Stopped the key being taken
*by A***J on 6 January 2026*

Our last one of these snapped after two years of general use and the exposed edges of the cable became sharp requiring some tapping up before it did break entirely. Ironically, master lock do not suggest using these in their key boxes yet obviously there are cases where they are required. Be prepared they do take up a little room so placing the key back in can be a bit tricky.
