I liked the idea of being eco-green with my chalk options, but its sticking power just doesn't match up to regular chalk's. It defiantly dries my hands to the point of chapping in cold dry air, but I was still slipping a lot more than with regular chalk.

Love idea

feels like little styrafoam balls, really weird compared to normal chalk, works great at keeping my hands dry but doesnt last very long at all so i seem to use more. i do like how you cant see a trace on the rock after using it though, but i would stick with regular chalk unless you have a secret problem you dont want people finding haha.

This stuff is great for climbing in areas with strict no chalk rules. It doesn't seem to keep your hands as dry as black diamond's chalk but it works well enough.

I like this stuff--I have never been an over-chalker, this dries my tips out just right. I climb a lot of sandstone FWIW, and it sticks well without the dust and discoloration of the rick!

I switched to the Eco Ball initially because I liked the idea of having dry hands but not marking up the rock. It's great for that but even better, I found it does a much better job of drying my hands and not caking onto to my fingers like normal loose chalk or a standard chalk ball. I now have a hard time climbing with normal chalk as my hands never feel as dry and clean as they do when I use the Eco Ball. The only downside to the Eco Ball is that it seems to deplete faster than a standard chalk ball. But that's certainly not enough to keep me from buying Eco Ball after Eco Ball.

This was the first chalk I bought for myself. I always used the gym's loner chalk, which felt a little unsanitary, so I bought one of these. I don't know if the gym's chalk balls were just over used, but this seemed to give me a much better coat of chalk, which helped my hang better and thus climb better. I can't speak to it's stealthiness since I only climb in the gym right now, but I hope to get out bouldering before too long, which is why I picked the eco-friendly stuff.

The Eco ball works great and leaves no trace so the adventure is there for other climbers. Only problem I had was finding the actual ingredients in the eco ball to figure out if there was anything that would cause it to stick to the rock and not wash off.

I love this stuff! I've used a number of different chalks and they all seem to cake up on my hands, and all over the rock. This eco chalk dries any sweat without gumming up my hands. Plus I've used it on granite, limestone, sandstone, and conglomerate and it doesn't leave any trace!!! Great stuff!

Hate it! I gave this ball away after one use, I like the idea but I hate the product. Just carry water with you to remove chalk marks from the rocks!

A little goes a long way to pull moisture from your hands (keep in mind my hands do not sweat much). An excellent choice when you cannot use standard chalk. I could not see any marks and I use less so buildup would in theory be less of a problem. It does feel different, so try it out to get used to it before heading out for a long climb.

I love the idea, but the product is awful. I used this wall gym climbing and fell off an easy route when I couldn't grip anything. I switched back to regular chalk and climbed the route no problem. If you have sweaty hands don't waste your money on the eco ball.

This stuff works just as well as chalk at restoring grip to sweaty hands on a pumpy climb. The label warns that this environmentally friendly chalk substitute might dry your hands out because of the strong drying agent which is used, but I haven't had any problems with dried out digits. With this stuff you can climb and save the environment - what more could you ask for?
