I am so pleased with this purchase. Assembly was straight forward and it has worked flawless from the start. This was the only machine I found that had a smoke extractor/filter, which incidentally, acts much like an air assist in keeping etches and cuts clean. The touch screen is responsive and the choice to use a direct connection, wifi or an SD card provides flexibility. I am using it with Lightburn and the only thing I want to add is an overhead camera. I might consider a more powerful laser down the road but right now this machine is doing all that I want.
