Poor Product By Brian on 8/21/2010
Brian wouldn't recommend this product to a friend
It is noisy, and poorly / cheaply made. All plastic including the prop shaft which was not straight on the one I got. Pump would barley move any water, it spent more time stopping and starting and ratteling. You get what you pay for! I have 2 of the magnums also and have been happy with those. I was enticed by the adverstised low power consumption and higher output listed for the evolution models. Other net postings I have seen complain about the same issues.
