Received in the mail yesterday, the camera slider is amazing! It's the same high quality as the bigger brands but at a third of the price of a trusted brand. Gliding is very pleasant and smooth, like its other characteristics. Drop-off wheel bearings allow the pulley to be manually moved up and down the railing. The bubbler is really great for leveling, so I know it's even flat or mounted on my tripods. Strong grip yet easy to move, very useful for my school film projects.
