Nah, haven't tried one yet... Wouldn't mind giving one a go though.
Do they work with video, Or only stills?
Nah both, the angle is quite good and when I've done it surprisingly stable....though I have the contour not gopro....only thing annoying is the constant view of the swivel or linesplit depending on how your brand does it (some better than others, bulky swivels etc. not much good). oh and pick your days cause recovering from any fashion of kitemare or other than dead simple kite crash is a pita.
