We have bought this machine and it's super good stable and nice,also also the laser welding machine ,it's perfect ,and what I can say ,the most import thing is the after service,if you have any problem with software,Jack is all there to help online,and at any time he will help you without any problems in english,but it's really.....I did not expected a customer service as fast and everything good,he will explain everything,go online if you have any questions,everything is super cool.
