This is a “review” of the ACMER R10 Laser Engraving Enclosure Box, uncompensated and purchased myself. My desire here is to provide hopefully, helpful feedback and information for users to consider. It's a decent value for its price range. Its design in its current state pretty much makes it airtight because of its zippered bottom and I didn't have any trouble with it being able to evacuate the smoke. The vent hose extends out to 8 ft, I didn't need to go that far so I didn't test that. The window material is the same color as any of the other...
