Review on DOMICA 25W Submersible Aquarium Heater for Small Fish Tank (1-8 gallons) + Free Thermometer Sticker: Efficient Heating Solution by Katherine Martin

The heater sent does not match the one pictured OR the box it came in. There is no way to adjust the temperature on the heater except randomly. The knob is very difficult to turn. You can't just stretch it out and twist it. The protective cap on the end of the tube broke when I put it back on. I am completely dissatisfied with the crappy product and false advertising. Unfortunately I have no choice but to keep it. I really wish I could afford to return it. Liar!
