Yes the lack of a vid showing its use would have been a very good idea !
I was under the impression that it was of similar size to the univalve , that you could connect it either between main hose and pole hose , or use it in a hoseless type set up where it would go up inside pole .
So i am really not sure now if it would be of any use to me at all ?
This is how i am set up , male and female rectus go up through pole as it is extended ...
