I was a doubting Thomas until I tried it. No matter how much I sweat this stuff just keeps the smell away. Don't know how, but it does it and does it extremely well. Even my overpowering Brut deodorant can't compare to this stuff for stopping b.o.!

I was nervous going from lifetime antiperspirant use to a "natural" deodorant, but wanted to try this after reading EWG's Skin Deep report. The price seemed reasonable and the roll-on form didn't bother me. I've used it through 90-degree days and workouts, and to my amazement it works. It doesn't leave residue, it doesn't mask you with scents, actually it doesn't smell like anything - it just keeps you from smelling. If you need to physically stop sweat, this probably won't work, but if you just want to avoid odor and let your body do its job, it's wonderful. I will definitely buy this again and recommend it to people looking for natural alternatives.

I've tried the solid crystals and the spray. They work well only if you put it on just right. The roll-on works perfectly -- absolutely no odor, most likely because you get full coverage when you put it on. No guess work.

So far, so good. Being concerned for my health, I gave up my long time favorite Secret and switched to another so-called natural brand with below average performance. Crystal works very, very similarly to Secret. No sweat during the day, no B.O. - nothing. It does take awhile to dry - so maybe put it on right out of the shower. I will purchase again!

I used to get large, painful lumps under my arms with conventional antiperspirants. However, I disliked deodorants because I always felt wet, and still had body odor. With the Crystal Deodorant I have no lumps, and no odor. I still sweat, but somehow I rarely feel it. It has to be a really hot day, or I have to be really active. However, even at those times, there is no smell. My father had Alzheimer's, so I am especially thankful for the lack of aluminum!

This is the best deodorant ever. I've been using it for almost 8 years now. My mother told me her secret as to why she always smells good. She told me it had to do with these deodorant crystals. I would use an additional antiperspirant when I know I am in for a high activity, but this definitely takes away the odor, and it is unscented. I would never give up this product. I have stayed stink-free for as long as I have used it. Sure, it takes a while to dry, but the results are satisfying. Use it after a shower for maximum results against odor. Believe me ladies and gentlemen, this stuff truly works.

I've used this for more than a year with no irritation. And it works!

I've been using this for a couple months and it has been consistently working for me. I like how it's natural and has no fragrance. It works all day for me. The only thing I don't like about it is that it takes a couple minutes to dry. I prefer stick deodorant, but this one has worked so well I'll keep using it.

I love this deodorant stick. I have tried tons of products including other all-natural ones. I sweat, but as humans we're supposed to. I have no odor issues with this product, and it doesn't burn me because I don't shave my pits anymore. YAY for all natural products that also do not test on animals.

I am still amazed that it keeps me stink free without any perfume. Plus, as a woman, I can wear tank tops and not worry about the white residue I get from all other deorderants. Right now I am visiting Thailand in the summer (HOT and HUMID) and my Crystal Roll-On is holding on from morning to night, without any touch ups! I get rashes from others, but not this one.
