Narrative:

Upon touchdown with a normal rate of descent; the ram mount detached and fell towards the area directly in front of the outboard rudder pedal. This required the pilot flying (PF) to move his thigh to the outboard sidewall to trap the ram mount and prevent it from hitting the floor and potentially interfering with the controls. The captain noticed the ram mount detach and as the PF began to verbalize passing control the captain who took the aircraft at approximately 100kts.the ram mount was attached to the elb on a C model aircraft. It's a glass surface if it doesn't work well on that by an average user it really shouldn't be in use. I have yet to talk to a single pilot that is satisfied with this mount that routinely detaches in light turbulence. In my opinion this device has introduced another threat to the cockpit that outweighs its benefits.
