A solid,well-made life saver!
A very solid,well-made sensor,which works extremely well. Note: the alarm is extremely loud,and in my small kitchen/diner,even with windows open,cooking has set it off.Lesson learnt,but I would not be without it,so this device stays located near to my gas boiler.

The fixing screw holes are very small, the previous models had proper size, also the volume is not too loud ( hopefully just the test is this quiet)

Just put battery in and you can use on mantel or wall

Excellent delivery service for a no nonsense product. This comes sealed with a 10 year battery. It's also very small and free standing, so it suits if you prefer a minimalist aesthetic and no holes in walls.

Looks great and is very easy to place an remove when needed somewhere else. Haven't been able to try the real CO measure, but the test alarm works fine (maybe too loud),,
