Good service. Good product. The courier delayed my international order and though it was ordered via Amazon (they were not helpful at all) Brilliance team replied to us instantly and patiently worked with us and replied promptly to get the product delivered. So great for service. I haven't don't very extensive trial yet. But was happ to see it helped a nice dark marking on 10w diode laser. Without Brilliance it was only 50% as dark. Waiting to try on other metals.

The additive is good but doesn't make… The additive is good but doesn't make the laser marking black enough or white enough but it definitley works.

Super service and product works great! Changed the product to one that could ship to my APO and still meet my needs. Constant updates on shipping and replacement. The best service I’ve had in some time. Thank you Brilliance. The product works great. Still tweaking it's use though. BTW I use a 40W Diode and it burns great at speed of 9000mm/m and 60% power on thick aluminum business cards. Thank you again.

Good product, great staff. Was leary about the product and I am just starting out in the laser engraving field. They sent me 2 samples, red and black. Both work as advertised. Will be purchasing the product for continued use.
