## Customer Reviews

### ⭐⭐⭐⭐⭐ Lockmaster Milamaster Centre Case. Easy Fit, Works Perfectly
*by J***  on 22 September 2025*

Installation was quick and straightforward. I also replaced the lock barrel and handles at the same time, and it all came together without any issues. It took me around 10 minutes to fit everything to the door, and the mechanism works smoothly.Very pleased with this purchase – a solid, reliable lock that’s easy to install and restores full function to the door.

### ⭐⭐⭐⭐⭐ Ideal replacement
*by G***E on 17 August 2025*

Perfect fit, hopefully it lasts longer than the original part it replaced

### ⭐⭐⭐⭐ Cheap back door lock gearbox
*by S***G on 5 February 2025*

I last bought this product in May 2018 and am replacing it again today. One of the cams broke into four pieces on the old one and it wasn't worth trying to source a spare when the new lock was less than £17. Even with next day postage it was still half the price of the closest supplier to me and it lasted 6 years so I think that represents reasonable serviceability from what is after all, a cheap lock. I think the open case design is not great as it allows debris and dirt easy access to the mechanism and I have had to grease it a couple of times over the years but for the price, it is still good value for money.
