Please be very carefull before buying from this company.First ask the correct questions, I have lost 36000$ when I bought a machine and are struggeling with them to fix it for past 1 1/2 years.Also they cannot give you answers and delay the repair.It took 6 months to get engineer to fix my machine because their software was wrong.Now the machine worked 90 hours and laser is to weak to cut.They dont replace and cost will be on you!!For emails, Questions before buy of a 3D laser machine and communication between me and them feel free to contact me at [email protected] and I will be glad to give you information. read full review »
