I've not used them, I've had a complete set and set them into the guides to see how they work. I liked the idea, but still......my skill freehanding a dremel is fundamental at best. lol I guess I could practice on a POS cracked head.

Heck, we ALL got our feet wet that way. I encourage you to give it a shot.
