They are bad ass... I ordered a handful for all my Star Trek Machines. They are very hard to see if you don't have external lighting. The best are proably the half/half because they strobe when rolling. I do love me some black pearls; but have stopped using them at shows.
Other than the tracking issue... the other issue I have with them is they are hand-crafted. which means no two ball are the same... and the insignas on the balls are not show accurate. A pet-peeve for my Star trek collection.
I hope to get some new ones in the future... or make my own.
