Just a few years ago, a fiber laser engraver was something that cost tens of thousands of dollars and only just big companies could afford these wonderful machines. But today, thanks to the advancement of laser technology, even a small home business or a hobbyist can own one of these laser marking tools.

Full written review: https://hobbylasercutters.com/commarker-b4/
A fiber laser engraving machine excels at engraving metal and plastics. It is precise and 100 times faster than conventional laser engravers. I have thoroughly tested the new and very affordable ComMarker B4 20W fiber laser engraver which delivers a lot of performance for its money with its motorized focusing Z-axis, live engraving preview, two different lenses, a rotary system, a foot pedal and handheld capability. It can also engrave in color!
