In addition to our smoke and carbon monoxide detectors/alarms,
I am very happy to have the additional security of this gas detector/alarm.
It gives us the extra peace of mind knowing that we are about as safe as we can be.
To verify the unit was operational, I tested it using an unlit propane torch.
It worked exactly as described. The digital display clearly showed the gradual rise of gas
and the alarm functioned as described.
This a very good product, at a reasonable price,
I recommend to everyone that has any form of gas fired equipment
in there homes or businesses.
