Review on Tetra HT Submersible Aquarium Heater: Efficiently Regulate Temperature with Electronic Thermostat by Nick Owens

I wish I could give 0 stars which I never did before. I bought it exactly a month ago, it kept my 2 gallon tank at exactly 78 degrees which was great for my beta, he was happy and enjoying life! I just got home at 11:30pm to find him dead, which broke my heart. Then I touched the tank and it was HOT and I mean HOT even for me. I looked at my thermometer and it read 90 degrees. It literally set my fish on fire. I'm so mad and angry. You buy a product designed to help LIVE life and it kills it. DON'T BUY WHAT YOU DO.
