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 Teresa Carter

Unfortunately not for long. Originally purchased in December '19. Had to send it back in January 2020 for a replacement which arrived 01/10/20. I stopped working on April 27th, 2020. The seals don't have to be very good as I believe water will get in and short out the electrical elements. The digital reader always reports only one error. I do not recommend this heater as it is simply poor quality and not durable. I've had other heaters for a number of years and they still work. Skip these. When it worked, it worked fine. Unfortunately, it's too late to replace it and try again. Glad I caught him before he killed my fish.
