Compact and simple to intstall and test This is not as stylish as the NE Gas supplied unit this replaced, but I hope the lifespan of the sensor will be as good.

Ordered two detectors following having our chimney swept. Your company as recommended by the chimney sweep. Arrived within a few days. Seems like they are doing the job they are meant to do.

Seems good value and instructions clear and helpful. I found it easy to test the device using smoke from a cigar and it was reassuring to know that it responded appropriately. The device is small and portable (potentially for holiday situations).
