Customer ratings
Serious power and quality
Setup was straightforward, and this 70W laser is incredibly powerful. It consistently delivers top-notch results on wood and acrylic. Although very expensive, I highly recommend it for anyone who wants to do laser cutting seriously.
Review 2
The auto-focus cutter saves a lot of time by ensuring each engraving is spot on without manual adjustments. The huge 850×800mm bed fits my big projects, and the build quality is excellent. It is a heavy machine, but it handles detailed designs and large cuts with ease.
