The slider is smooth but can precisely control the movement, making it very durable. I like it best when I'm shooting on uneven surfaces. I can adjust the height and angle of each leg separately to get the most consistent shot possible.
Pros
STRONG AND LIGHTWEIGHT DESIGN: The camera slider is made of high-strength carbon fiber rails and stainless steel flywheel, durable, lightweight and not deformed to achieve perfect sliding with precise motion control. Comes with a quality storage bag for easy carrying and portability
