Review on Effortless Video Shooting: TARION Y5D Autodolly Electric Slider Motorized Pulley Car Cine Dollies Rolling Skater with Wireless Remote for DSLR Camera, Video Camcorder & Smartphones by Jeff Apel

Nothing with wheels rolling on the surface can happen without a slight wobble. It'll be light years better than anything portable, and if you're an amateur or a pro using this device, adding some warp stabilizer will give you buttery smooth video. Too often, reviewers' expectations are simply too high. I didn't buy any of these last year based on the reviews and now it's an absolute must have in my travel bag. I would add this to the must-have list for most people, especially those without a gimbal or image stabilization.
