There are three undeniable comments in the reviews, which I've also experienced:1) A hollow, metallic ping every time it bounces. I'm playing here at a university indoor court, and every group of guys I play with has commented "hey, this ball sounds weird." When the game ball is chosen, this is the first they toss away. The ping has the quality of the inflated "Thunderstix" that are distributed at MLB playoff games.2) A regulation full size ball should be inflated between 7.5 and 8.5 lbs PSI. This Never Flat ball seems to come on the low end of that. Despite only receiving it two weeks ago, guys at the gym have all said that it bounces flat. Although nobody wants to hear whiny comments about their new item, I have to agree on the lack of bounce. Over a year of this before I can inflate it??3) Having read others reviews, I now understand why I'm typing with small cuts on my left index and right middle fingerpads. It's on the rough side for bballs.
