Buying 2 gave a very competitive price. Easy to fit and uses AAA inexoensive batteries. Too soon to comment on durability

Great feel safe now

Hope it works, if not we're in trouble.

The units were fine.

I started using these alarms many years ago now and from experience, they really do last as long as they say they will. They are so easy to install as well so, there really is NO reason not to fit these in your home this weekend and sleep safe in the...

These carbon monoxide alarms are great and do work, sold as a pair (with batteries) . Great value for money and can be placed anywhere around the house .

good product

It was to replace an old and expired carbon monoxide alarm

Great value twin-pack of essential alarms that every home should have.

easy to use
