I have been so please with this laser and it has worked well for me. The XCS software is still a learning curve since I am used to lightburn. I have ordered the D1 extension and ready to do bigger projects. I would like to have the enclosure with the extended part but can't afford it now. I already have the small enclosure but with the new extension, I need to have the extension for the enclosure. All in all this is a great experience with this laser and company.
