This mount has nice, big suction cup: http://goo.gl/PYKiqS (but way too big tablet holder for 7 inch devices) while this mount has really nice tablet holder http://goo.gl/DEtwgk (but not that great suction cup) so this adapter combines both of them into one 7 inch tablet mount with big suction cup.
