“Suction cup mount” eh? Looks like some 3M double-sided tape to me…
And you’d be correct. 3M VHB double sided tape seems to form a permanent bond according to 3M from their website. Whoever the engineer is at Fiodio ought to be “Keel Hauled” !
"With 3M™ VHB™ Tapes, you can maintain consistency from sketch to construction, eliminating distracting, visible fasteners, like screws and bolts. These high-strength, double-sided acrylic foam tapes let you quickly and easily create a long-lasting bond that actually builds strength over time. With the ability to join a variety of materials including aluminum, steel, glass, plastics and painted and powder-coated surfaces, they provide resilient bonding solutions in just about anything you can dream up.
Personally I prefer the tape to a suction cup, especially for a two-camera system where the rear camera is connected to the front camera by a cable. The camera snaps into the mount, so you can detach it if you want. The tape isn’t permanent; you can remove the mount with dental floss and a lot of patience.
Tape also allows a lower-profile mount.
