I don’t know about you but I like them a lot! When first the right bobbin came out back in 1994 (if I remember correctly) I know that it would be the best bobbin the market had to offer and at that time was a real innovation. Thread tension control, full ceramic tube and a single leg. One think I had to do was inserting one on each side of the spool a silicone washer so that the thread would run smoothly. To day the bobbin comes with it.
