Purchased this as a replacement for one which had come to the end of its life. So fitted existing base unit. New design allows you to change battery without taking out of the base.

Looks like most other devices , easy to fit, loud distigution alarm siren

I was looking for a Smoke/Carbon Monoxide detector and this was just what I was looking for at a reasonable price...

a good device only problem was knowing where the best place to site it big cost saving buying on line outside store on mobile then paying in store

Having both in one is a great idea, neat looking, clearly says fire, the hush button great idea, no more taking out battery to shut it up after you burn toast.

have only tested unit, looks good .Tells you which problem you have whether smoke or carbon monoxide

Easy to install and it talks to you!!!!

This combined alarm for smoke and carbon monoxide is easy to fit and unobtrusive. I am hoping that it will never activate for real!

Very pleased with this smoke alarm with its built in carbon monoxide facility would recommend to any one

Good for value product, fairly easy to fit. Handy to have the battery tab in the front of the device to make changing the battery easier.
