## Customer Reviews

### ⭐⭐⭐⭐⭐ Super easy to use
*by K***Y on 22 November 2025*

Delivered 2 minutes ago and I’ve already fixed my letterbox with them! Easy to use and a perfect fit

### ⭐⭐⭐⭐⭐ easy fix
*by C***0 on 10 January 2026*

Did the job of fixing the letterbox easily

### ⭐⭐⭐⭐ Needed slight filing down to fit
*by K***Y on 17 February 2023*

The right thing, but just very slightly too large at hex and lug (perhaps 0.25mm?) so had to carefully file down to get to fit, but after that all seems good. Otherwise exactly the same as the original ones (which is good and bad as the plastic does break, but probably needs to be plastic to give flex and tension for it to work correctly) in the letterbox on my somewhat ageing uPVC door's letterbox
