Did the article chewed after I read a lot of good reviews about it. Had before cheaper parts (15) and thought the new controller makes it better. So ... buy 3 pcs and lo and behold -. The old regulators have well regulated, the new were totally confused. Once too hot, then too cold. Very annoying and useless. Am now gone back to the old regulator. New and more expensive is just not necessarily better (useful)
