easy to assemble and disassemble gravel over a large area 33cmx19cm the software is easy to use I love wifi mode Just like all engravers, you have to make your adjustments before launching the engraving. test on iphone shell, aluminum and even glass it works on the other hand it is necessary to blacken the materials in order to engrave them and even make several passes if necessary. (laser 20w electric -5.5w optical) test on the cutting of thin wood , paper, cardboard and even on a seal sheet to redo motoculture breech joints all without problems. On the other hand, don't expect to make landscapes where even faces in 5 minutes, it takes a lot of time , everything also depends on the size of the drawing.
Arrived quickly, assembly took approx.15 min. It's my first laser tool so I am learning it.
