Review on 🌡️ Inkbird ITC308S Aquarium Temperature Controller with Submersible Probe, Thermostat for Heater and Cooling Fans - Heating Cooling Outlets by Mariana Vasquez

I bought this because those crappy Ehiem-Jager heaters are garbage. Mine was set at 74 and kept heating up to 86! Rather than break the bank for a better heater I bought one and it worked great for controlling the power of the heaters. I only connected a heater, no fans. The temperature in my tank doesn't vary more than 1°F from 77°F in either direction. It is also very easy to program.
