Yes I have the Pfaff Expressions 4. I've had numerous problems with mine. I bought this machine for a lot of the bells and whistles. Can't use the auto thread cutter because it gets stuck half way (dealer told me to get used to it because it was going to happen a lot), can't use the needle threader (can't get the wire loop to go thru the needle), have to constantly re-thread top thread and re-insert the bobbin. When I try to find the solution to a problem I'm having and the so-called "manual" is pretty much worthless. I have probably over 50 spools of Gutermann thread (made in Germany) that do not work well in my machine. Just used my first spool of Mettler metrosene plus thread that seems to be working better. I've had my machine for 2 1/2 yrs and still feel uncomfortable with it.
