There is a learning curve to using it just like there is a learning curve to doing FMQ. I got really frustrated with it yesterday and yanked it out to do a particular piece I wanted done. It will skip stitches and I have yet to determine what I need to do to stop that skipping. But, I did a king size quilt with it two weeks ago and had no problems. The skipping is due to user of course - -LOL
I am not trying to talk you out of it, but just want you to know it is not the magic wand for FMQ that some think it is.
