Since I didn't put the money out for it, it's hard for me to say. That and the fact that we are just learning. I can say it gave us the ability to quilt with designs instead of just stippling/meandering or marking the top. I haven't played much with the software, but did make a design for a friend. She hasn't been able to come over and see if it works out though.
It doesn't help that we have trouble with the machine itself. On more intrique patterns it breaks the thread a lot even with the same thread top and bobbin. As a result we have been sticking with the simpler designs. We have had a lot of thread problems with this machine(Pfaff Grandquilter) even before Qbot. My sis bought the Pfaff because we both have older Pfaffs and love them. Sorry I can't be of more help.
