Review on 🌡️ Inkbird ITC306T: Advanced Dual Stage Heating Thermostat with Submersible Probe Sensor for Aquariums, Reptiles, and Greenhouses by Amanda Love

Works as expected. I bought two Tintevogel heater thermostats to regulate my 3 gallon tank and my 10 gallon zebrafish tank, each of which I use 2 Top Fin Betta 10w heaters. Calibration is fairly easy, and there are YouTube videos that explain how to set it up. I used an accurate thermometer which I first checked with an ice water test (32 degrees Fahrenheit / 0 degrees Celsius) and then calibrated my sensors accordingly. I also keep an extra aquarium thermometer in each tank to ensure the temperature is accurate. Definitely recommend to anyone wanting better temperature control (especially when using non-controllable heaters) or wanting to protect themselves from heater thermostat failure that can occur with controllable or non-controllable heaters.
