I had a 5W laser that came with my cutter frame. Intrigued by the 10W+ system I made the plunge and I have to say I noticed a vast improvement in both power and control. Any issues were quickly answered by George. Yes you can get ‘high power’ lasers from China at lower cost but add in the control, the air assist and the technical backup from Endurance and I know what I would choose…Endurance Lasers.
