I had one, and it takes time to get it rolled, etc. just like with a long-arm. The problem comes because your domestic machine is limited by the space under the arm. If you have a newer one with more space, that's a tiny bit better, but the take up roller has to fit under there, and the little bit of room you have left - that's all the space you have to quilt. While the theory is good, I never used it much. Not enough quilting area.
