The suction cup mount is practical, well-adjusted and locked. Holding force is good if the surface is clean. By the length of the cantilever vibrations are hardly avoid. Is very good that a standard UNC screw (tripod thread) was used: Thus the holder also for other things (flash, video light, webcam) used. The adapter then allows also to mount the Hero example on a Gorillapod.
Very convenient.
Materials and workmanship are a bit worse than in GoPro, but fully acceptable.
