I have not used that specific Current USA product, but I have used their lighting products on my FW planted tank. I found the lighting I got to be decent as far as the LEDs used and color spectrum, but the controller they have for them leaves a tremendous amount to be desired. The control for the pumps your looking at seem to be a similar kluge. I note the limitation of 3 pumps and a real lash up of wires, and the lack of control from your computer or other mobile device. In their favor they are inexpensive. Ecotech or Tunze would cost about twice as much.
I'm not saying don't get them, but do investigate the control of the pumps very carefully.
