Review on 🌡️ 3 Mini Digital Thermometer Hygrometer: Accurate Indoor Temperature and Humidity Monitoring for Your Incubator, Reptile Tank, and Plant Terrarium by Ryan Foxz

Like other reviewers they were already activated as soon as I received them. I currently have 2 in the incubator and in the pictures they are all within 1% accuracy (there is also a separate thermometer for checking measurements), the humidity is also within 1% accuracy so overall they are very good value for money offer money. I will only buy for humidity sensors as the temperature drops about 2% at times.
