I have one after testing sewing with it at the Paducah quilt show. Sharon Schamber was demoing it. She used two Halos together for precise control. One works for me. It helps when doing smaller detailed shape quilting. She said she put handles on it but the handles got in the way so had them removed. It's a heavy rubberized ring that grips the fabric and easy to move and to hold on to. I use it more to make perfect curves by quilting inside the ring edge. I don't use it for most of my quilting but when I need it, I'm glad I have it.
