This isn't the most effective deodorant by far, but it is all natural and doesn't have all the scary ingredients that the leading brands do. I prefer Body Mint tablets, but you may not want to ingest your deodorant! I think this is a decent alternative, and besides, humans do sweat and we do smell. Crystal deodorant will take the edge off that!

I purchased it based on the reviews and I am very disappointed. It didn't work for me, and I don't know why. I was not allergic to it(I am allergic to many others), but I was not protected against sweat smell.

This works pretty well in the beginning. It is definitely wet and leads to wetness in hot situations since it is not an antiperspirant and then after time doesn't do as good of a job staving off odor, even with reapplication. I would recommend going with the Kiss My Face Liquid Rock deodorants over this; I had better luck with that.

Just FYI, Potassium Alum is natural mineral salts.

effectively eliminates odor.

This deodorant works really well, however it goes on very wet which I didn't expect. Nevertheless, it is a great product.

I don't understand why everyone keeps saying that this has no aluminum in it. The ingredients say "potassium alum" which is aluminum sulfate. It clearly contains aluminum, so if, like me, you're looking for aluminum free, this is probably not the route to go. I was honestly considering it, until I googled the ingredients.

This deodorant is great. I was getting a little worried using those antipersperants that have so many potetially harmful ingredients in them. I started with the stick a couple of years ago that you have to wet a little and then apply. It was a bit of a nuisance, and I admit I didn't use it all the time. But then I found the roll on (don't know whether it was out on the shelves and I just didn't see it) and I've been a steady customer ever since. For someone who doesn't have an extreme sweating problem, and I live in south Florida, I find no problem whatsoever with using a deodorant versus an antipersperant. And I really like the fact that it is fragrance free. I've always hated applying those really smelly antipersperants and having them do battle with my cologne.

With so many great reviews, I bought this for my daughter and she hates it. She said it doesn't work at all. I bought 3 bottles, since I thought it would be hard to find. Turns out, they have a natural one at Target with a nice scent and she loves it! No go on this product!

I tried this and it works as well as other deoderants. It doesn't leave a hard residue like other deoderants I've used.
