To all the haters (or people who don't know how to use them properly): This works great for me on stainless steel, 4130 and aluminum. Just make sure you're perfectly level, just below the centerline of your part, LOW speeds, especially for steel alloys, and a light hand feed with some coolant. The thing is worth the money.
