I think it's worth noting that they say:
"Engrave Wood, Plastic, Acrylic, PCB, or Similar Material
Can Not Engrave Metal, Steel, Aluminum."
So they're honest about its capability, or lack of it.

These things will engrave metal including stainless you just have to go at it slowly. From my research there is a huge variety of CNC3018-Pro machines out there with differing control boards being the difference.
Some have later driver chips on with a finer resolution, some appear tohave the row of pins A1 etc on the bottom disabled which is not helpful if you want to use a Z axis mapping function.
For that reason I shall probably be buying the Sainsmart one which although a little more expensive has the latest iterations of components and supposedly reasonable customer support.
