Review on 🐠 Aquarium Heater Submersible Auto Thermostat Fish Tank Water Heater with Adjustable Temperature, Suction Cups, and Protective Case by Mylivell by Elizabeth Thornton

returned. Installed correctly. The installation is self-explanatory. The tempo is inaccurate. More importantly, it will reach the set temperature and then turn off. If the temperature dropped below the set value, it would not turn on. By the time you notice it, the day/night temperature drops a few degrees. The power indicator is also hidden inside the case. So you have to dip your hand in the water and pull it out to see if the heater is on. I recommend spending a few bucks more and getting a heater with an externally adjustable LED digital display.
