Review on 🌡️ Qooltek Mini Digital Hygrometer Thermometer: Precise Indoor Humidity Monitor for Cars, Incubators, and Pet Climates by Chris Bowden

I love this combo so much I have ordered several for different tanks. I glued a magnet to the back for easy attachment and moving around the tanks. My oldest has been working great for a few months now. UPDATE: Downgraded one star because it couldn't handle my high humidity tank. I've attached a photo of one I took from my poison dart frog variarium where the humidity is 100%. It's not clear why a device that measures humidity can't handle humidity and moisture. I will definitely not use them in higher humidity tanks.
