## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Easy installation and testing
  

*by J***O on Reviewed in the United Kingdom 🇬🇧 on 30 April 2019*

Bought to replace the exact same model so it would fit the existing wall screws - and it does. (The previous one beeped to tell it was at the end of its lifetime, which had been 2 years longer than the expected 7 years.) The enclosed manual/leaflet contained instructions in various languages. Getting the batteries in, testing the detector and putting it up on the wall on the existing wall fitting was easy... I hope I never have to learn if it works in case of an actual carbon monoxide leak.

### ⭐⭐⭐⭐ 







  
  
    Good buy!!

Bought one of these before, our reason for buying another. Good quality, works fine, good value 👍

### ⭐⭐⭐⭐ 







  
  
    Good job
  

*by E***E on Reviewed in the United Kingdom 🇬🇧 on 18 December 2013*

I've already got one of these and it cost £25 a couple of years ago.  This is identical and at 60% of the cost great value.  Easy to install, easy to test and appears to be a good piece of kit.  How do you know whether these work if you have no CO leak?  Hard to say but if no CO leak it hardly matters!
