Harbinger Humanx Chalk Balls

Have you used this chalk for 6 years and use it every workout . I have been powerlifting competitively for 5 years . I like this chalk . It provides great coverage and great grip feel . I would recommend putting the pouch in a zip lock bag for less mess

These have been terrific. A convenient way of chalking up hands. They don't give off a lot of chalk, but they are perfect for when doing exercises where not much chalk is needed.

I primarily use this for rock climbing. Gives a good amount of chalk and holds it in together nicely. Works as described.

They break apart and make a mess...don't buy. Period.

I'm giving a low review because of the claims made that the balls reduce dust and the MgO3 stays on your skin longer so less reapplication is needed. this is not true. the balls became extremely dusty after awhile. it's standard magnesium carbonate like other chalks, so it needs to be re-applied when you need to. i didn't find the cloth bag to be that useful, as the clip broke after a few uses and i had to put the balls in a ziplock bag. the bag can't be re-used because of the broken clip and powder being all over the bag and string so it can't be refilled and tied up.
