Oh dear, not good.
My rotary attachment is still bubble wrapped but mine is the simpler, cheaper unit with no chuck, just a set of stepper driven 3 rollers to hold a glass or bottle by friction.
Can't see it ever getting used.

I did see another one of the type you have on a forum somewhere, where the spindle had pulled out of the upright because the bearing was a loose fit but it looked an easy fix if you could get redress off the seller.
