Review on 🌡️ Rojuna Mini Thermometer Hygrometer 5-Pack: Large Number Fahrenheit LCD Display for Humidors, Greenhouses, and More by Steven Doty

One of the five devices stopped working the day after arrival. I think the batteries might be dead but I don't want to try to move the batteries to check them because when I opened the battery compartment it looked pretty cheap put together. So maybe it's not the batteries! I'll definitely wait and see if the seller reads this and offers to send replacements. If any of the four remaining units fail, I'll send them all back for a refund.
