### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very loud
  

*by W***N on Reviewed in the United Kingdom on 8 June 2024*

This product is very easy to install. It took literally 5 minutes to fix onto my door. The volume is very loud. It adheres to the door frame really easily. They're a good size and the quality is great. I have bought more of these for my parents house too.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Really noisy
  

*by M***E on Reviewed in the United Kingdom on 5 June 2024*

These are great, very easy to set up, pair and the installation was easy as well. I had a little play on the bench to see how far away they need to be as all my doors are internally openings. Once that was established i just stuck them on and away we go. They gave us a piece of mind, especially as the noise made the dog sit up.Living with them daily is also a doddle with the remote control, just like your car lock and unlock.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    3 doors didn't set together
  

*by M***H on Reviewed in the United Kingdom on 27 June 2024*

After an attempted burglary the police recommended individual door alarms.  As we don't have much room around the door frame to fit one these fitted the bill for size.But we have 3 doors and they all didn't set at the same time, despite standing at a centre point to them all.  So when one didn't go off, we went closer to set it and one of the others pinged off.The attempted burglary has really unsettled me and not being sure they're all set at night meant we have had to return them to get alarms that set individually.
