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.

A repeat purchase of the same item from several years ago, now expired. Totally satisfactory in terms of maintaining vigilance, but, thankfully, never put to the ultimate test!

Would have preferred to have lithium batteries as standard. Unit is quite bulky compared to other EI alarms, e.g., smoke alarms are slimmer and blend in better.
