I bought one online (not Connecting Threads) and loved it, but I have a Bernina and where I had to attach it to maximize the light, is right in the way when I am free motioning a quilt. When I do anything of any size, it rubs on the light and eventually managed to peal it off. They were great and replaced the light bar with the sticky stuff for me, but it is going to do the same thing next time. My suggestion would be to consider what kind of quilting you do, and see where you might have to attach it to your machine before purchasing. And just FYI the little ones that take batteries that JoAnn's sell, are worthless, they project almost no light.
