I have used this product for the last 10 Years. When I move home 10 years ago. I inherited a British Gas (BG) branded boiler. I then added a BG Gas Fire. For both of these I was issued with the Honeywell CO2 detector. BG are my selected boiler and Fire maintenance providers. They have never questioned the use of this detector. They work and pass yearly inspections. I seen no reason to change brand and product.
