It's the cheapest you can find follow focus on the new internet, i think. 51st all included. It's very good for the price, a little bit of wiggle, of course, will not be ok if your lens HAS kind of a stiff focus ring (like my old 60 micro nikkor) goal for AF lenses qui in general HAS smooth and easy turning focus ring, you will be happy. The next one will be the Fotga 500IIs, Where you can adjsut the stiffness of the follow focus and the 'natural room / wiggles' that can APPEAR over time.
