I have this camera dolly ordered by chance because the price was so tempting. Meanwhile, I have I can make some nice camera work with it. The dolly moves pleasingly light is quiet and easy to adjust to a curved path, not just a straight movement as we know it from small rail dollies or Glidecam.
The only drawback: To align the axes again exactly a straight movement, a lot of sensitivity and therefore time is needed. Therefore, a star deduction. I would like to see a snap point at which the wheels or axles are aligned for a straight motion.
