Complete security on a single device
I bought this 8-in-1 carbon monoxide detector because I wanted to have greater peace of mind at home, and the truth is that it has exceeded my expectations. I love that it not only detects carbon monoxide, but also natural gas, in addition to showing temperature and humidity on its very clear and easy-to-read HD screen.The alarm is quite loud, which gives me confidence that it will be heard anywhere in the house in case of an emergency. It is also very practical that it can be plugged in directly, without installation complications or batteries to change all the time.I think it’s a very complete device for home security, compact but with advanced functions. Now I feel calmer knowing that my family is protected. I recommend it 100%.

Buy this if you want your house to blow up
Plugged it in and it cycled through to baseline, great I thought, it works. Fast forward 24 hours and I notice it is reading 8-10 degrees warmer in the room than it actually is. Who cares, that’s not why I bought it, but a bit of a bummer that it doesn’t work. Another 24 hours go by and I think I smell gas in the kitchen where it is plugged in, three feet from the gas line mind you. Certainly my gas detector would be going off if there was a gas leak. I try to ignore it as it wasn’t an overwhelming smell. Another hour goes by and I think I smell gas again. Figure I should call the fire department, better safe than sorry. I am fully expecting them to tell me everything is fine, I just have gas on the brain because of my new alarm. Wrong. There was a gas leak and they had to shut the gas off to my house. If you value your home, your life, or both, don’t buy this. It doesn’t work.

I’m so glad I bought this carbon monoxide detector! It was super easy to install just plug it in and it started working right away. The digital display is clear and easy to read, and I love that it gives me peace of mind knowing my family is protected. It’s compact, reliable, and even has an alarm that’s loud enough to hear anywhere in the house. Definitely worth every penny for the safety it provides!

Carbon Monoxide & Natural Gas Detector
Great little portable detector for CO and natural gas. Measures PPM with a very high pitch alarm. This unit is perfect for areas that are not well covered by your existing CO detectors. The screen is very well lit and easy to read. It plugs into any 120V electrical outlet but it does not have battery backup. Easy to set up and good deal for the price.

False alarms. Not to be trusted
should have read the reviews before buying this detector. Might have saved a service call from the natural gas company today. There was no smell of gas at all. Suddenly out of the blue it was sounding alarm for high numbers of ppm of gas.technician could find no trace of gas and told me that the readings I got would have been a very strong smell. So my entire household was disrupted for a false alarm. What a waste of money. I’ll be tossing it and taking my lumps if Amazon won’t refund.

Impressive multi-functional air quality detector
This is a very impressive multi-functional air quality detector that sense carbon monoxide detector for carbon monoxide concentration, natural gas concentration, along with temperature, and humidity. It constantly monitors the air with two sensors and provides rapid alert response when air detection thresholds change to dangerous level. The alerts are voice descriptive and loud level of beeping that we alert the whole level of the house. I like being able to constantly monitoring the temperature and humidity on a clean looking digital display – see picture below.Overall, I recommend upgrading your old CO2 detector and enjoy the comfort in knowing your gas is also being monitored as well – not to mention at a great price!
