After multiple attempts to upload software which kept crashing and freezing, I have spent many many hours trying to get this thing to work. The laser DOES work, the program that you need to use does not. You can’t adjust size correctly(kept saying size was more than the equipment could do but that wasn’t true) I have watched many videos that offer help but all show assembly of the machine and a program that isn’t the same as what is required for this model. IMO, don’t waste your money. Very regrettable purchase.
