The machine arrived on time without damage and packed good. It is a China made laser to be clear. Set up was time consuming with aligning all 3 mirrors. There is a lot of manual knobs to use and adjust so on my 12x20" 50 watt unit it took several hours to get laser fine tuned. The engraving was not very crisp. Whether it was the lens or the laser power quality I'm not sure. Customer support couldn't help. I used poplar and the wood tended to burn and was inconsistent throughout.

The laser head has an air line attached that actually hits the right side of the machine so that limited the work area (image).

They advertise images and dpi claims (4500?!) that are misleading to this lasers actual raster capability. The best engraving results I was able to achieve was engraving speeds of only around 250-300mm/sec.

Laser engraving machines are indeed more expensive. Even for the same power laser engraving machine, the price difference before different brands is very big. Based on my budget, I ended up buying an OMTech 60w laser engraver(https://omtechlaser.com/products/60w-co2-laser-engraver-cutter-usb-6r57-us) for some small projects. Enough laser power to use, large working area, auto-focus.
