I bought one in November and it's being sent back to Pfaff via the shop owner
Everything was fine until I tried to FMQ and the bobbin broke a few times. It also started skipping stitches. Did all the usual things until finally I took it back to the shop I bought it from and she had the same problems. She tried a few recommendations the technician made by phone to no avail so off it went. Here's hoping I'm not going to be continually beset with problems...........
