It works fine, except as noted for the bobbin . It has a piece broken off of it. Was planning on taking it to a dealer to see if it could be repaired, but then discovered how to hold thread when winding that works fine. Other than that, no mechanical problems. Seller had good reputation on line.
The first one is a mechanical one that I bought off goodwill online. It too works very well except for same problem with bobbin winder. I like that that one does not have a computer board, and may outlive the newer one.
