"aeroponic" cutting system

Anybody tried this?
I know its not aeroponic but just wondering on feedback.

Im not sure what gimick makes it work there is no air pump .....

The description said there is some sort of pump, I think it works by the end of the cuttings are in the water and the pump puts oxygen in the water, instead of the cutting being above and getting sprayed or misted. I wouldn't spend $150 for that, I have a spray type cloner and got it cheaper and its works beautifully!!!
