I have the same question as Cindel. My box says PQ-1500S, my machine says Nouvelle 1500S. Have only tried FMQ once and have tension problems due to light weight bobbin thread and standard thread above. But pretty much got that ironed out. Foot that came with it seems really long and does not have much bounce. I thought I had it on wrong, but there really is only one way. Don't like it like I do my open-toed one I use on my Kenmore/Janome.
