I thought I was buying a unique hockey ball that was "no bounce", had liquid in it, and heavier than a standard hockey ball. Not true. These are the same exact thing as any other street hockey ball you buy, just at a premium. I almost feel as if I must have been shipped the wrong product, but after checking in, apparently not. False advertising. I play ice hockey 5 times a week and was looking for a good street ball. I hope this helps.
