Board of Director
I've used this flow controller since it became available in the US. It's by far the easiest way to control the flow on your water fed pole. I've used other methods with varying degrees of satisfaction and can't say enough good things about the Aqua Dapter. I know some have been a little put off by the cost (about $140) but I just found out that they have decided to go direct and the price for a new one is now about $70. In fact they have a new website you should check out here.
