Review on 🌡️ Mini Probe Hygrometer Thermometer: Digital LCD Display for Reptile Tanks, Aquariums, Greenhouses, and Babyrooms - Fahrenheit (℉) by Bob Boan

I need a few to keep my guitar cases wet but I wanted to try one first. Yes, they only show the temperature in Celsius, but only the humidity really bothers me, so that's not a problem for me. The remote control cable is longer than I need, but it's easy to hide. It seems pretty accurate, but I can't know since none of my other devices read the same thing. It looks like the block is designed to fit into a rectangular hole in wood or plastic. I strapped the reading to the pen of one of my soft cases for easy reading without opening the case. I was surprised the device was on when I opened the box, so I don't know how much battery life is left. It must have been an open box. I will have to order more of these - very handy and should help protect my investment.
