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.

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.

Good product for Stainless Steel engraving Give me surprise results with my 10w diode. But some of the coating may be blew out by the spray air during spraying procedure. Take time to learn.

DO NOT WORK WITH COMPANY !!!!! The product didn't work as described. After requesting a refund and return label i received the runaround. After responding to several emails (10) the company cut off Communications. I have now started a dispute process with PayPal. DO NOT WORK WITH COMPANY !!!!!

Great Experience There was no problems with ordering and my order was delivered promptly as described.
