Good gadget which can save your life during trips
Easy to charge and use.Perfect size for traveling.Good size display.I bought it for a vacation trip after being scared by the news of people going as they slept in resorts due to CO levels.This little gadget also tells you about humidity and temperature so it is very functional.The magnet was not strong enough to hold the weight of the gadget when I tried to attach it to my fridge.The battery lasted during my trip because I only used it at nights.

Doesn’t detect CO2 at all!
Bought it specifically for CO2 detection. Anyone who has passed high school science knows that CO2 will not read 0-4 ppm in any environment. This plainly doesn’t work every picture on here is 0000 ppm.I put it next to my SwitchBot CO2 and gave them over 30 minutes to get a reading this CO2 alarm reading 2 my SwitchBot 1263.Returning it.If you just want temperature and humidity it’s fine.
