The first test was loud enough to hear upstairs, so I placed the detector beside our garage door

I bought one for my mum’s utility room, and she liked how simple the plug-in setup was

I keep this alarm in our small rental flat, and the red lights are easy to notice from the sofa

I tested the CO alarm after plugging it in, and the warm-up finished just as the guide said

Clear display, easy test, reassuring in our kitchen

For our garage fridge corner, this detector gives me a clear display and a loud warning I can trust

After fitting the alarm near the kitchen, I could read the display easily while cooking with gas at night

We added the sensor before my father came to stay, and checking the numbers has become part of my routine

My wife and I use the sensor in our caravan, and the loud test sound made us feel properly covered

Plugged in quickly beside our gas cooker
