Hi
I have the 5x7 and the larger snap hoop for my Babylock Elegante and I love them! I use it for embroidering towels and have used it for quilting on a lap size quilt....nothing larger....yet! When I have something that I know would be hard to hoop or I don't want hoop marks on it I grab my snap hoops.
I usually figure out just where I want my design to go, put the hoop on the machine, and then align the item in the hoop. I don't use it for embroidery applique and I always make sure I have a full bobbin before I start. I don't want to have to remove that hoop from the machine and chance unaligning the project.
I use them often and really find them useful.
