Review on 🌡️ Accurate Aquarium Temperature Measurement with the Pinpoint American Marine Calibration Thermometer by Bobby Montoya

It has been over a month since I first used it and I wanted to wait that long before writing a review. At first everything was fine, I didn't need to calibrate as the readings stayed around 0.1-0.2 degrees Celsius compared to my other calibrated digital thermometer. But after 2 weeks I noticed that my other thermometer was deviating more and more from the norm. It got to the point where the difference is about 2 degrees Celsius! Now I have to calibrate it once a week to keep the readings under control.
