Reliable and Easy to Use!
This 4-in-1 gas and carbon monoxide detector is a must-have for home safety. The color screen is clear and easy to read, showing gas levels, temperature, and humidity all in one place. Setup was simple—just plug it in and it’s ready. The alarm is loud enough to be heard throughout the house. Great peace of mind for our kitchen and RV.

It’s work correctly
It works correctly. I did a test with a burnt paper, lit it and then put it out, letting it produce smoke. The device alerted me with its alarm. I’ll order another one!

Have mixed feelings about it.
This is kind of difficult for me to review because I’m not sure how accurate this thing is in detecting carbon monoxide.. I will have it tested by the fire department perhaps but one complaint I do have and it’s a bad complaint.. this thing doesn’t stay plugged in. It’s designed to just fall right out.. very weird. I’ve since had to tape it to the plug..Another thing is it tells the temperature but the temperature has been way off. And it gives my area is having high humidity but it’s a pretty dry place..
