I agree with this statement!I use controllers as a tool, not the life line and heat beat of my systems. They are machines built my man and will eventually fail.
for all of you that hook up this stuff as if your tank would blow up and not work are frrekin nuts lazy and have forgotten the roots of the hobby.
Old school here and i bet if your toys crapped out you'd wet your pants and wouldn't know what to do.
Its only a high priced TOY to play with and have fun with
