Easy to install. Test system works Difficult to know how to rate this item when brand new as it is a cm detector with a number of years guarantee. Ask me again in 2026 to see if it is still working!!

I assume it will work I cannot say if it is a good product until it detects CO. However, I can say that the flashing light is very irritating in the darkened bedroom and I have placed tape over it.

Great products, great service, great website, why go anywhere else? As somebody who has a technical brain (I am a chartered engineer) but no knowledge of this product except that it is a necessary safety accessory for any home. I was presented with two alarms in our home that displayed warnings that the batteries were at the end of their useful life.
