## Customer Reviews

### ⭐⭐⭐⭐⭐ A quick and easy unit to mount for ones safety indoors with a woodburning stove.
*by G***D on 9 February 2025*

A nicely made unit with a good instruction manual and everything needed to mount it to the wall. It took but a few minutes to install and test this device. I feel safe knowing that if there is ever a carbon monoxide build up I will be alerted by this little alarm.

### ⭐⭐⭐⭐⭐ Wisualarm CO Detector review
*by D***G on 28 April 2025*

Seems like a reliable product but until it detects CO and does what it supposed to do can't say for sure if it works. Passes the functional test ok.Like the digital display feature but only displays data after performing a functional test then goes off.Would like to have put it on the ceiling but not an option in the user guide so put it high up on a wall.

### ⭐⭐⭐⭐ Good, simple detector
*by J***N on 14 December 2022*

It’s too early to judge battery life, but the detector is simple to view and test. Let’s hope it’s just as good at detecting CO.
