I wanted to attached my Go Pro to my sports car while driving but i thought the one suction mount that you can get was overpriced and so i designed this tri mount. I bolted the flat mount to the tri-pllate. i used three of these suction cups from eBay http://www.ebay.co.uk/itm/251457943518?var=550369684172&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Works like a charm.
