I used this temperature controller in my 210 gallon salt plant with an 800w JBJ titanium heater after the expensive JBJ digital controller gave up the ghost after only 6 months of use. I'm not a big fan of digital controllers as they are very sensitive to power line problems, surges, surges and the like. I had connected a JBJ device to a small UPS to protect it from such interference, but it still failed. Must be bad quality. Not what you would expect from a $200 heater. So far the Finnex HC-0800 Analog Controller has worked flawlessly. The device looks and feels very premium and performs just as well as the JBJ digital controller but at a fraction of the price. It has yet to stand the test of time, but I have a feeling it will.
