## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Secure and easy to instal
  

*by A***R on Reviewed in the United Kingdom on 18 October 2024*

Needed to urgently secure a upvc back door where the lock had broken. These were easy to fit with self tapping screws (no need to drill) and provided a great, secure solution. How task took less than 20 minutes. Would definitely recommend and would buy again if needed elsewhere. The only downside is, of course, you can now only unlock the door from the inside so will eventually have to get it replaced but at least it’s secure for now.
