Have left freestanding so far. Seems to be working fine. Really should have bought one when I moved here. Every house with gas should have one.

Does what it says good quality stand alone feature worth the money

This is a good product, bought due to a currently temperamental boiler, the alarm went off before you could smell the fumes - a potential life saver - definitely recommended...

Easy to assemble and understand how it works. To be honest great value for money.

Overall, a very good product. Good make and model.

Easy to fit .

Exactly what i wanted and needed, what i really like is that it states the amount of carbon monoxide in your house and if your anything like me thats a weight off the mind with a visual aid. Easy to set-up, looks great.

This product is excellent and easy to read and set up

Bought this for the digital display and I find it useful. Could be another case of boys and their toys though.

good value for money pleased with item for money paid
