Very well made.

I enjoyed the handling of the Perfect Manipulation Balls right out of the box. Trust me, if you grew-up on the wooden balls with the enamel paint - hard and slippery - you know how much easier the silicone ball is to work with. For those who do the move, as an example, the 'Elevator' flourish is effortless and secure with these Silicone balls.

For me, the weight of the ball is perfect - not too light, not too heavy. The gimmick matches in color and feel perfectly too - perhaps these really are 'Perfect' Manipulation Balls.

I also appreciated that the BL PMB set is priced a bit less than the comparable balls of this quality and price-range.

Another thing that makes this ball set attractive is that there doesn't seem to be the re-stocking issue with this ball; whereas, with other balls, if you don't get all you can, when you can, you have no idea when or if the other higher-end Si Balls will be back in stock.

This may not matter to everyone; but to me, when it comes to something like Billiard Balls (or Fanning Cards, Silks, Dove bags and harnesses), once I land on the brand I like and work best with, I don't like being forced into something else; simply because no one has you need - sometimes, for a very long time.

So the fact that this ball does not seem to suffer from chronic out-of-stock syndrome, makes up a good part of my decision to stay with that ball and get more; or, regret my purchase as 'unusable'.

I've one more ball set I want to evaluate before I 'land on a brand'; but the other one is... you guessed it: 'out-of-stock with no foreseeable re-stock date.

So, Bond Lee's Perfect Manipulation Balls are leading the pack on price, performance, and being in-stock more often than not.

Good ball set, good price.
