I wanted to get a laser etcher but did not have the room for another machine in my small study. So I looked for a laser unit that would attach to my printer. Research took me to Endurance and their products. I found Endurance to be very professional and they answered all the questions I had about the use of their laser units. Fitting was straight forward and the software was simple to set up. Within a short time I was up and running. I am very pleased with my purchase and I am confident that I will be using it for many years.
