Yes, I bought one just like it, from the same seller I think. The bottom part just sits on the table and the top cross rotates. After a while or for some yarns, it does skootch a little acoss the table, but not by much.
But, I do notice that sometimes the bolt tightens itself. Anyone else notice this on theirs? If the bolt is twisted all the way down, it's locked in place, so you unscrew the bolt some so it can rotate. But I have found that sometimes during winding, the bolt will start to screw itself back in, so that I have to stop and unscrew it a bit to loosen it up so it will continue to spin.
