I have it and never use it. My reason is that for a measured (after ironing) 1/4" seam I have to move my needle position. Can't do that with the single hole plate.
I don't have a problem with the machine sucking the fabric into the wider slot if I use a starter piece. I also position my fabric right up to the needle (I always start with the needle in the down position), and this seems to help too.
It's possible I might start using it again if I go back to garment sewing though, I can see it coming in handy then.
