I have three of them. One controller crapped out and wouldn't turn on at all, another crapped out and wouldn't turn off, the third still works fine. I cut the heater portion off of the controller on the two defective ones, installed standard plugs and now operate them with my Aquatronica. They work great now. Biggest advantage is no risk of glass breakage, but they seem to be no more reliable than standard heaters, perhaps even less.
