As far as our process is concerned we design engineer our own laser machines in house then select proven laser components for manufacturing and assembly. After we thoroughly QA each machine we proudly warranty it 100% - and our reviews speak for us. While we strive to keep our laser machines affordable, we do so without sacrificing quality or usability. We're not interested in promoting "functional", low quality, laser units that force you to figure out a home made fix to get operational. We're setting a standard that we are proud of and one that you'll appreciate and rely upon for years to come.
