No. I have a Sailrite I fight with at work. It is an over hyped, made in china, proprietary multipuropse feet that don't work well in the real world, piece of junk.
The feet ar horrible for anything but new contruction and you can forget about going over a seam because the feet design makes it nearly impossible. If you watch the videos for Sailrite they are making a bunch of new items or patching a flat area, never fixing anything the least bit difficult.
It will not hold tension, no matter what I do or what needle and thread I have tried.
I finally broke down and told my boss I hated the machine and bless her heart she said "well you've worn it out. Buy what you need."
Save yourself 700.00 of heartache, headaches, and disappointment. Don't buy a Sailrite.
