Review: Works - Works well, tried it on two Co2 detectors, one brand new and one about 4 years old
Review: Does what it should - Well I got this and thought what a joke there is nothing in there, I was wrong as it sprays! The alarm was taken down placed in a bag couple of sprays and bag sealed and the alarm sounded the Carbon Monoxide alarm. This provided the peace of mind that I needed to know my alarm work, very easy to use, good value for money as I’ve not been able to simulate an alarm without this. Does what it should good quality easy to use!

### ⭐⭐⭐ Expensive peace of mind
*by C***R on 17 August 2024*

I finally got round to complying with the Scottish requirement for interlinked alarms and I bought this to test the CO detector. How long does a typical 400ml can last? If you're planning to squirt this around the place like an air freshener you'll be very disappointed. I got four 3 second bursts out of it and I am being generous to the last one only because it was enough to set my alarm off. Oblivious to how little was in this, I did the sandwich bag test on the CO detector as soon as I activated the battery. I then proudly showed it off again later to my other half. When my first heat detector arrived I linked it and tested again. Luckily by my 4th test everything had arrived and I had linked up every one of my smoke and heat detectors. I managed to verify everything was working, but that was the "400ml" can empty.
