Being brand new to laser engraving I spent a bit of time comparing machines.
So far I'm very happy with my purchase. The machine itself functions perfectly. Delivery qas quick and setup very easy.
I did struggle a bit with the software uploads (firmware) and am still not sure I did it right, but it works.
I would recommend pitting the different firmware upgrades on different drives (especially how cheap they are) to help alleviate problems.
