Customer ratings
Powerful machine for the price
Cuts 10mm wood cleanly in one pass and engraves with excellent detail. Great value overall.
Assembly was easy
Setup took under an hour and everything worked as expected. Instructions were clear.
Good performance but noisy
The laser cuts well but the air assist pump is louder than I expected.
Impressed with color engraving
Managed to create beautiful colored patterns on stainless steel. Definitely a highlight feature.
Manual focus is tedious
Power is great, but I wish it had autofocus. Changing material thickness slows down workflow.

Its large work area and smart air assist are standout features, though users must be prepared to implement their own safety enclosure and fume extraction.
