Review on Yost Heavy Duty Drill Press: Powerhouse Performance for Precision Drilling by Darrell Beecher

You will receive this product in packaging that is likely to be damaged, it is a vise after all. There's nothing wrong with that, except that it doesn't come with instructions on how to install it on the press. It contains no hardware and the jaws only move in one direction, so your vise and work material must be perfectly aligned under the drill to ensure accuracy. To be honest I don't think it's a very practical or drastic improvement over some clamps and some scrap lumber given the price and lack of mounting hardware and instructions.
