I was so lucky to have chosen this laser engraving machine! The positive things I can say about delivery time amazingly fast, it makes me feel very surprised. Most important, this machine cutting function is very good, this cuts themselves seem pretty good, I've only really tried to cut some 1/4" birch, and the laser will cut right through it in one pass. The machine doesn't have a lid interlock, so it is possible to open the lid while the laser is on and it doesn't turn off, don't do this.If you want these machine, do not hesitate to buy it, it is amazing !
