I needed a rolling mill for a wood working project -- to roll out some brass to a uniform thickness. It works flawlessly. The instructions that accompany it are very clear with plenty of photographs that make it easy to get up and running. There's a lot of grease to deal with when it is unpacked but everything arrived in pristine condition. Lastly, the packaging is bullet-proof -- the middle box (yes there are three) is covered in woven polyethylene tape.
