About other similar products, this is the worst. I do not recommend it for any sport, there are better options

It is excellent. It provides a thicker layer of protection against dust, and the specific packaging has a different nozzle than the smaller one (bottle), resulting in no clogging.

Some negative reviews that I see obviously come from unrelated people, as one lady wants to stay on the pole (obviously for pole dancing) and the other wants to stabilize the handle in deadlifts (I have never heard of such a thing), which obviously happens due to incorrect grip. The use of chalk is done to prevent sweating of the hands, so that they do not soften and consequently do not tear... In deadlifts, the bar is stabilized anyway, neither chalk nor any other magical powder stabilizes it!
