There are lymph nodes right behind your arm pits which chemicals can easily absorb into. Some intellegent people suggest the aluminum and other harmful chemicals in anti-persperant and other deoderants are related to lymphoma, cancer of the immune system. This product is made with only natural minerals and nothing else.

My 7-year-old son has always been a heavy sweater and had problems with BO from an early age. All of the adult deodorants were really harsh and made him break out in rashes and didn't work at all anyway. I decided to try this out after reading the reviews and I can't believe it! It has worked like a charm since day 1. No more embarrassing BO and no more rashes because it is so gentle. Even after a day of running around and playing with his friends all day, there is absolutely no smell and he has never even needed to reapply it. Please give this a try, you don't have anything to lose!

This is the only deodorant I can use that works. Before I found this, no matter what I used, I smelled. I have used this for many, many years and never have body odor. If they ever quit making it, you'll know because you'll be able to smell me wherever you are.

I prefer the "rock" - an actual crystal deoderant that I buy at [...]. When I use the roll-on, I stink at the end of the day. When I use the rock, I don't. May work for some, but not me.

This is a great product. I have tried several brands of aluminum-free deodorants and this has been the only one that has actually kept me feeling fresh all day long and did not break me out. My boyfriend who is workaholic and constantly on the go also uses this and loves it

I have been using this product and Naturally Fresh Deodorant Crystal (I've only found it at GNC stores) for years. I don't know what I'd do without them. I have sensitive skin under my arms and normal (even non-antiperspirant) deodorant irritates me after a week or so of use. Not this stuff though! It has no scent, keeps me from stinking, and doesn't irritate my skin. My only complaint is that compared to the other deodorant I mentioned above (the GNC one and it comes with a blue top), it doesn't last an entire day (the GNC one does). I feel like I end up smelling a little B.O. by hour 9 or so. Nothing intense, but you can tell it's wearing off. All in all though, a great product.

Both my husband and I suffer from allergies and have been looking for a deodorant with no fragrance. Not only does this one have no fragrance, it works really well - even when we work out. And, there is no underarm residue transfer to our clothes. We highly recommend this product. (As a side note, we also tried the stick, but at times it was irritating. We have no problem with the roll-on.)

This is the first natural/bad-aluminum-free deodorant I've had work for me (and I've tried quite a few, including Jason, Kiss My Face, and Tom's). It does not smell at all, dries very quickly, and is completely clear. It does a really good job as a deodorant; if I work out or otherwise sweat a lot, I do start to stink a little, but it's perfect most days. Definitely worth a try,.

My son has extremely sensitive skin and cannot tolerate antiperspirant products. They make him break out with a bad rash. This product solves the problem and has virtually no order and does not contain irritating perfumes. He says it works great and is the best deoderant he's found so far.

This is the only deodorant I have been able to use. Every other deodorant I have used has made me break out or caused an allergic reaction. I have used this product for 6 years and I haven't had a problem, yet.
