What you've got in the aqua are basically two posts, each post with a nut that sits on the top of the post, and a center portion of the post where you want to wrap your leg so that it is secure. You do this on each side, tightening down the nut so that it is pressing on the legs keeping them in position. You CAN really get the hang of it after a while and it becomes easier and you find your own methods/techniques to get the two coils mounted on the posts properly. The only real significant downside I see to the aqua is it burns through juice quickly and doesn't hold much to begin with.
I would not fully discount an Aqua, even though mounting dual coils can be a pain at times, and even though they are best used when airflow has been increased with some airhole drilling. I have used/owned a lot of devices and my drilled Aqua is the best device I have ever used.
