GH aeroflo36 aeroponics garden

I am just about to buy one of these units... I have looked around online and have found few people documenting their grows with one of these.
I had a friend with a 'rainforest' and was totally blown away at the growth rate of both the plant and its root system.
Anyone seen one in action or 'has a friend' with one? Any info would be appreciated.
