The Pros:
This product works. In terms of effectiveness, I would give it 5 stars.

The Cons:
As many people who search for unscented products know, companies can use masking fragrances and often do not have to explicitly list them on the label. I'm not bothered by the scent in this product as it's very, very light, but it's something to keep in mind.

Also, the product contains the same aluminum ingredients in all mainstream antiperspirants/deodorants so if you're looking to get away from them, this product is not just baking soda.

It doesn't leave a white mess everywhere if you apply it carefully after getting dressed. But, it does not exactly go on clear.

Bottom Line:
We've spent plenty of money trying to find unscented deodorants that work. Most of the "natural" ones don't. Even with the issues noted above, this is the most effective product we've come across.

The deodorant works well, is non sticky (though a little thick). My only complaint is that the deodorant is not domed, it arrives concave with rough edges. Yes you drag the deodorant across your body the rough edges flake off. It takes several days of use before it forms a smooth usable finish.
If you have sensitive skin, this is not for you.

I got this 2 pack to test. I am very happy with it. When I put it on, there is a white residue. Not bad, but kind of. I wore this with a black shirt. After an hour, I took off the shirt and examined the armpit of the shirt. Didn't see any residue and after checking my armpits, no residue. I decided to do some testing. The residue lasts for a very short time but the protection is all day. I'm a heavy sweater and my son is very sensitive to odors, so I've been looking for something that really protects, doesn't leave my clothes messy, and doesn't smell. I am very happy with this product. Some people have said that the screw up part or the part that raises the deodorant was broke on theirs. I am almost done with my second one and no problems. In the past, I've always used the old spice and have used several different ones, but even the nonscented one was noticeable to my son. This one passed with flying colors... so to speak.

Unfortunately for a scent-free product there is a very strong chemical fragrance odor that emits when I sweat. So bad, the scent was disturbing to others at a meeting and I had to put my jacket on so people could focus on the meeting. I'm usually a fan of Arm and Hammer but not sure what happened with this product.

I am on a medication that causes me to sweat excessively leading to odor and social anxiety. I tried every clinical strength deodorant I could find, none of them lasted more than 2 hours before I sweated them off. I was about to ask my doctor about prescription deodorants, I took one last look at the stores selection and saw this. the anti-sweat ingredient (sorry I can't remember the name) is 19% instead of 20% making it not "clinical strength" making it $5 cheaper!!! While it can be slightly drying, I just switched to applying the deodorant only to my armpit instead of my entire underarm/armpit area. This is THE ONLY deodorant that has met my needs and I buy it in bulk. It has allowed me to do what I want and get through the day without sweat-stains and anxiety. Thank you so much.
