It is not recommended to purchase.
It looks good. The readings are clear and easy to understand. This device was purchased mainly to detect the carbon dioxide in the propane heater I use for heating. I’m very disappointed with the temperature readings. I might have to return it.

Seems to work and do what it says
Needs time to adjust to the air temp and such before it shows correct readouts. Still trying to test it on a source of CO. Otherwise giving it 4 stars for battery life and features. Flashlight function comes in handy.

Inaccurate Temperature Reading
Looks nice. Reads easy. Left the house at 66 degrees went to the shop where it’s 40 degrees. Took an hour to get from 66 to 59. (Screenshot is a Govee thermometer) mainly purchased this to detect co with my propane shop heater. Disappointed with the temperature reading.

CO detector not working
I blew smoke at this under several conditions including in a small space to test the CO detector nothing budged it from registrating zero. I’m disappointed bc the size and other functions are spot on but if the CO detector isn’t accurate, it’s useless to me.
