I told one of the other members on here, I would recommend using a smaller plate to hold your dye bed. I'm talking a maximum of 1/2" larger around than the discs you dye, when it comes to sc dying.
There are a few review floating around however we have not released discs yet until we make sure everything is perfect. We want to make the most premium and consistent discs and this takes a little more time than one would think since we are just getting off the ground floor. Our first disc will be approved to the 180s because of its diameter so that's the heavy weights.
