I did what Uncle Sam did: take a piece of 320 or 400 grit wet/dry paper and spray-glue it to the bench. Then lightly rub the scale around until all four "feet" are touching evenly.
That little Lee, while leaving very much to be desired, will be more accurate than your digital. In fact, when my digital doesn;t match the Lee, I check the digital scale. Once in awhile, the Lee beam will find its way too close to one side or the other of the magnet, and will give a false reading. Now that part I don;t like.
With all that said, I'd love to have $100 or so that I could dedicate to an RCBS 10-10 scale, because I surely would.
