Here's my feelings about them, and they kept me in a bad mood for some reason. What I found is this, with my new eye prescription, I can clearly see the sharp edges of ball numbers on any of your average or high end ball sets....but my eyes cannot pic and see and exact spot on the object ball, weird and I'm not impressed. Now the diamond red logo on the cue ball has nice crisp edges, but nothing else about the ball set is define, nebulous at best, perfect word to describe the balls markings and outside edge of obj. ball. It feels like they are glowing NOT in the dark.
