Anyone know the NEJE A40460?

Hi
I have heard of this laser:

It seems that it can engrave on stainless steel:

Stainless steel direct grayscale engraving: Yes
3D hardwood engraving: Yes
Maximum cutting thickness: 20mm

They say the wavelength is 450nm, which make it a visible blue - violet light.

Does anyone have some feedback about its capacities? Thank you.

I’ve seen one person on here who’s marked stainless with a diode…
