Review on 🐠 Hygger 500W 300W Aquarium Heater for Freshwater and Saltwater, with External Digital Display Thermostat Controller and Thermometer, Auto Quartz Submersible Heater for Fish Tank by Angel Yergeau

This is my second. The first one broke and almost cooked my fish. The second temperature dropped and the tank stopped heating. I will never buy this brand again. The first one I thought was just defective and I was disappointed that there was no refund and it worked for 3 months. I'm very frustrated and should be able to return the second one but can't because it worked for a month. The reverse window is closed. I have had 5 tanks in my house for many years and many different brands of heaters. This has never happened to me with any other heater. Luckily I have thermometers in all aquariums and check them regularly. This product is terrible and they don't support their product by offering refunds for defects. You lost my business.
