This is a great product. I would purchase it again however I wish that you could order specific parts for it. There is a pen that you have to use before you put in the burr and tighten it and I lost it pretty quickly and there was no back up for it so you have to purchase a whole new set if you happen to lose that one piece so that’s the only criticism I would give but it worked great it did exactly what it said it would.
