I have them also, but do have some reservations about recommending them to anyone with a small (9") throat space. I find I cannot use them on the take-up roll as they take up too much room and I run out of quilting space too quickly. So still have to pin the top. However, because I used velcro for the leaders, I can take the leader, back, batting and top over to a table and pin them there. Also, I have a hard time getting them to snap in place because I just don't have the strength in my hands that I used to have. But with that said, I still wouldn't give them up.
