I use mine and like it. The quilting does go pretty fast, once you're set up. I DON'T like setting it up--like the tip about pinning to leader though, I'll be doing that from now on! In fact, I'm in the middle of setting up right now for a quilt.
I have purchased the longer poles, but have not tried them yet. That's the draw back; for bigger quilts, you do need a lot of room to move the frame back and forth.
All things considered, since the one thing about quilting that I HATE is sandwiching--this has been a good solution for me.
