    Easy assembly, directions were very easy to follow. Download light burn and easy to setup. Tested it out and did my Sasquatch for my cutting boards.

    I am a beginner and this laser engraver is equipped with everything I need. I USED GBRL SOFTWARE WITH A MAC SYSTEM AND THE CONNECTION WAS EASY. When cutting wooden blocks, I find it as easy as carving planks. And the effect is not bad, it is a good laser machine.
