Review on 🌡️ Veanic 2-Pack Digital Hygrometer Thermometer with Probe - Large LCD Display for Temperature & Humidity Measurement - Ideal for Incubators, Reptile Terrariums, Greenhouses & More! by Jeff Richardson

Just arrived today! They were already running when opened. I would rather have a pull tab to start the battery so hopefully this will last a while! All 4 came with a suction cup mount and double sided sticky pad. I mount them to my walls to control humidity with spray foam along with temperature. It's more than perfect! There are slight fluctuations in humidity, but it's okay :)
