A friend gave me a Lee "Safety Scale." It easily changed weights on it's own. I got rid of it.
Lee makes some good items, I don't think this is one of them. I'm much happier with my older Hornady.
This is my opinion as well. It ain't worth the price, even if it comes for free. I have several Lee items on the bench, and am happy with all of them. But their scale is not on the list.
