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.

Super Customer Service There has been a significant delay in getting the product to me. But customer support has been fantastic, I’m very impressed by the responsiveness and genuine care for my situation.

Settled with the speed of a lightning Settled with the speed of a lightning - ordered on monday afternoon (US), picked up on wednesday (central europe). But with the small orders the price of shipping almost reaches that of the goods.

Problem with the Adhesion of Ink Had a problem with the Brilliance ink bonding to raw aluminum. Had a great call with one of the service reps and was able to improve the adhesion dramatically. He had a great understanding of the process was able to help me through.

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.
