I love them so far, great flow, and as you said very easy to redirect. The magnets are a nice addition, you don't have to worry about suction cups, and they are easy to move from outside the tank. The only problem is that my tank is about as thick of glass that you can have and still have the magnets hold, I actually had to take the rubber part off on the outside so that they would hold better. I wish they made them in different magnet strengths because if you had thicker glass they wouldn't hold. Other than that I have been very satisfied with them, wish I felt comfortable putting them on a wavemaker, Woodstock does and she hasn't had any problems so far, so I'm following her thread. The other worry is that the outlet is so big I don't want a fish to decide to lay in there while they are off, and then they kick back on again and
