The Revo Tabletop Dolly is a small platform with 2.3" smooth-gliding skate wheels that can handle up to 25 lbs. Mount your camera in one of the 3 ports along the base of the dolly and still have two other 1/4"-20 ports to mount additional accessories like mics or lights. This kit comes with an articulating arm, ball head, and a smartphone mount. It will move fluidly in straight and curved paths or in wide circles. There are scale markings on the platform you can use as your guide when adjusting the axles for different movement patterns. This is a great accessory for adding movement to your footage.
