Review on 🌡️ Veanic 4-Pack Digital Aquarium & Terrarium Thermometer: Precise Water Temperature Meter Gauge with Water-Resistant Sensor Probe for Reptile Turtle Incubation Systems (Black) by Dawn Sherman

I was looking forward to that. The inner suction cup works great but the outer one keeps falling off the tank. It doesn't read properly either. I've tried two of these and they seem to work for a day or so, and then the temperature sometimes changes 10 or 15 degrees every few minutes. It went from 81 degrees to 65 degrees and then to 94 in about a minute and a half. It was without me setting anything in the tank, just looking. My analog thermometer did not adjust the temperature. I don't know if I will buy them again.
