Review on 🌡️ CHIVENIDO Wireless Indoor Outdoor Thermometer, Mini Hygrometer for Car, Greenhouse, Baby Room, Freezer - Battery-Free Hanging Hygrometer, 2" Diameter (Golden) by Chris Bailey

I bought this for my mother but had it shipped to make sure it was simple and accurate enough for her. It's surprisingly very accurate, maybe 1/2 degree from my house thermostat. I haven't been able to check the humidity yet. I love that you can adjust the temperature and humidity readings by turning the dials sideways with a flathead screwdriver if needed to make them more accurate (I don't need it) and that no batteries are required. Her apartment doesn't have a thermostat, and during the last Texas freeze, her power went out and she couldn't tell me how cold it was in her apartment. It's fairly easy to read and big enough that I don't need reading glasses, but it's all no bigger than the palm of my hand. What a great device. She will love it!
