Great stamp. I bought it to support JK. I don’t know if my disc has less particles or if I got a lemon, but this disc is not usable for night rounds, which is what I got it for. Yes I have the right light, but even sunlight yielded poor results. MVP customer service just kept saying it won’t glow as good as eclipse, which I understood and accept, but the pictures did not reflect that it would be unusable it should have been made clear that was their expectation, because it was not mine. I called G3T about an exchange since it was unthrown, but they said they were out. Hopefully they add an eclipse rip to future versions as that would seemingly be the best way to have a good look and practicality.
