I have the Singer Confidence 7470 low shank snap on presser feet.  This gathering presser foot fit perfect.  I did not have any issues with attaching it at all.  Just needed to remove the snap on piece to remove that whole part so I could put this one in its place; as it is attached to its own shank.  So this will fit this model with no issues.  Of course I just started to play and even without instructions I was making my gathers.  Still have to practice because you need to know which stitch widths and lengths and all you want for what type of gathering you would like.  I will need to see few videos again as well on you tube.  I will also write some notes on my widths and lengths so will be much more easier rather than using up scraps to keep thinking which one I liked for what.  Attaching the second piece of fabric that you would use so a flat piece of fabric is sewn right to the gathered piece of fabric at the same time is a little tricky.  I need to work on that one before I attempt to do a project like that.  Holding that piece so it is even isn't that easy and trying to figure out the size difference in your fabrics so your gathers and reg. Match up in length is going to take some practice and notes.  I would say it is a must to do your practice pieces and TAKE NOTES so your not spending so much time On each project trying to match it and adjust it and all.  It fits, it's great, it came fast....Only hard part is just learning how to use it for what you need it to do.  I really like this gathering foot and can't wait to see what I will master and create with it.
