I bought one and in less than a year it started acting weird. Found out it was the temp probe. Ordered a replacement, only to have that one die within six months.
I scrapped the controller for a Ranco that I was going to use with the titanium heater that came with the JBJ, but I noticed my tank never gets below 76 or above 80, so it's been sitting in the "fish box" for a year.
So, my official opinion is - save yourself some money and buy a Ranco Controller. After researching those, you can't really go wrong with them.
