Review on 🐠 HITOP Adjustable Submersible Aquarium Heater for 10-35 Gallon Tanks - 50W, 100W, 120W by Jennifer Rosell

It's certainly ugly with bright orange accents, but it's priced right and it works well. The temperature adjustment knob is accurate enough for slight temperature changes, and the output power is the same as the rated power. The grade lines drawn are not very realistic, but I did not find the tank heaters where they are. If you regulate the heat, you should have a separate thermometer or thermometer strip. This is a common problem and manufacturers would be better off just giving you guidelines rather than giving you the ever wrong degrees. This is a good option for the price. My only complaint is aesthetic.
