Review on 🐠 Premium Submersible Titanium Fish Tank Heater with Intelligent LED Display and External Controller - Rubor Aquarium Heater by Abdul Jorge

I have purchased two of these heaters, 300w versions. One works fine BUT the other light was on indicating the heater was on and also reading the temp. I set 77 degrees BUT it didn't heat the water and I lost my aquarium because the water was so cold. The heater only lasted a few months. I bought it in February and it broke at the end of April. Guarantee for 30 days but lasted about 60 days. (UPDATE) The company contacted me and sent a replacement heater, that's all I can ask of the company. For this reason and also because the other heater is still working, I have changed my rating to 4 stars. Maybe it was just a defective heater, that kind of thing happens. For the record, I would not hesitate to buy from Rubor again or recommend their products.
