Works okay. Great for the price. Not sure how the other ones work as they are all well over $100 but this will hold a six inch by 3 inch diameter piece of wood okay without flipping out or moving as long as you are gentle with the gouges. Use it to make spin tops and some toy parts. Picture shows clamps reversed from mine.
