We just used this product at an adult birthday party and we had great fun with it. We did run out of discs with only 12 players, so I'll buy a booster pack before the next game. Also, there's no way to latch closed the ball dropper, so it would be easy to lose balls when they spontaneously fall out. We have it taped closed for now. Now that all the packets are open for each part, we've replaced some with resealable baggies to make the next use foolproof. It all went back into the box for easy storage. It's too soon to see how the printed numbers are going to hold up on the balls, but so far so good.
