Review on 🐠 ZEETOON 300W 500W Aquarium Heater with 2 Artificial Plants 1 Stick-on Thermometer, Fully Submersible Titanium Fish Tank Heater for Saltwater/Freshwater Tanks 10-120 Gallon by Sharon Weston

Bought two in October, both died in January. When it worked the temperatures held up well, I used my own temperature controller to control them so it's hard to tell if they're accurate. Heated a 220 gallon garage tank, garage drops from 60s to 50s. I suspect one or both were basically working 24/7. The user thermostat turned on one when it dropped below the threshold and the second, turned on when the tank dropped below the second threshold. I bought a used Finnex many years ago, it worked forever, just died when it was knocked out of the pan without anyone. to know.
