I have a Varios-6 and super pleased with it. Best things is has more features than the Vectra and cost less. Quiet, slow start up, APEX ready out of box!(just need cord), well built, DC, feed modes, variable speeds, built in float switch device, cool intake screen, easy disassembly, large impeller, large ceramic bearings, box includes several output fittings, separate control and power. I needed a APEX ready pump and don't like the wavelike quality and the Vectra needed a separate additional APEX module. This way my pump is programmed to slow on my APEX feed mode with one button push. Love the pump, I highly recommend it.
