Review on 🚀 Tetra: Revolutionary Invention for Enhanced Efficiency and Performance by Judy King

Don't Buy This Heater! I had one in my 10 gallon tank with my betta and measles cats. It got out of line and literally cooked my fish! I was devastated when I entered the room and found all my fish were dead! The thermometer on the side didn't even register the water temperature. I took a thermometer from one of my other tanks and put it in a 10 gallon. He immediately heated up to 100 degrees! It may have climbed higher, but the thermometer couldn't read a temperature above 100. I am still heartbroken at the loss of my precious fish. I just don't want anyone else to go through what I did. My advice: stay away from Tetra heaters.
