I can't tell by the photo, but I have one that looks similar to this one. The one I have is a bobbin winder from a commercial machine mounted on a board with a motor and a thread stand that looks like the one in the picture. That one looks like it might be an upgrade of the one I have.
The one I have don't wind evenly either, but at least I am standing there watching it and can sort of "help" it wind even by putting my finger on the side of the thread and moving it slightly as it winds. I usually wind enough bobbins for a whole quilt at one time.
