I have a Babylock Quest and have much trouble; but I know it's the dealer. I had bobbins that didn't fit. And when I order special feet, I bring them home and they don't fit. Their fault but it's so depressing. For instance, I wanted the foot that sews circles. I was so excited. Doesn't fit the Quest. That's happened three times with this dealer (only one here) and I found the special feet originally on the Babylock website which refers you to your local dealer. Bummer!
