I have one, but I'm less excited about it.
I tried Rio, Penguin, Hagen, Aquaclear, and Maxijet powerheads. FWIW - the MaxiJet was the only pump that starts quietly with this thing during my herculean trials to get it running quietly.
I's sort of like to have some bigger powerheads on there, but the MJ seems to be the only one that is suitable.
Otherwise...seems like a good unit. The 'soft start' feature is sort of a joke though.
