I put it on my office desk to monitor the air, especially in the fall and winter when windows are often closed and ventilation is poor. This small device is light and professional, the alarm sound is not intrusive but clear enough, and the red light is also conspicuous.

For the health of my child, I put this in my baby's room. The real-time air quality display allows me to see the value changes at a glance even at night. Once the battery was running low, the indicator light came on and I knew it was really considerate.

It was my first time to install the device by myself. I didn't expect that I, a clumsy person, could do it by myself! The batteries and screws provided made it easy for me to install it. I got a fright when I tested it. The sound was so loud that the cat downstairs ran away. But I feel more at ease when I cook because it is guarding the kitchen.

Alarm works as intended. Comes with sealed batteries. Needed to place smoke detectors in every sleeping area for a home inspection and while not the well known brand, still has the same features that come with those brands. Good dual CO2 detector plus smoke alarm.

I installed this sensor today. Installation was simple, about what anyone would expect. Screws, anchor plugs, and batteries were provided in the package. It tested properly and made loud, annoying beeping noises. The sound made me grimace and I was much happier after the sound died off. It was very alarming.
