I probably got a defective product because as soon as it was opened it was completely dry and had no sense of deodorant, no matter how much I wet it.

Perfect. I apply it after the shower while my skin is still wet. After using it and during summer, I have to say that there is no sweat smell at all. It really has no scent, which some people might not like

At first it works perfectly, no bad smell, after a while it doesn't last as much, I think all stones do the same for me. Maybe it's not for me

Two stars because it works for me BUT the packaging is unacceptable, even though I was careful not to let moisture get in, the crystal broke off from the base on its own!!!

Unfortunately, although the idea of a natural product without chemicals was very nice, it does absolutely nothing, at least for me. I am surprised that it works for others, even in the summer...

I bought it because I wanted some kind of natural product but I was disappointed. It is an odorless thing. You wet it and use it on a clean body but I did not notice any kind of protection.

I have been using it for over a year and I am absolutely satisfied. It has never let me down. Of course, I will continue to use it.

I have been using this for several months, for winter it is fine, for summer I might look for something else as it does not work well with intense sweating

I am really impressed by the comments because for me personally I feel that it has done nothing... I still smell and sweat normally...

But deodorants caused me irritation and pimples with fluid. This particular deodorant has not caused me any problems. It lasts and does what it promises.

I give three stars for two reasons: first, it doesn't smell at all even though it says it has a green tea scent with aloe, and second, because the head is not rotating and it is easier to break if it gets wet often; it needs to be wiped every time to stay dry. Other than that, it does the job, but I consider it expensive for the small size I got. I would definitely prefer something plain and larger next time

Very very good product. It does not cause itching or anything else. Easy to use with a little water and lasts a long time. I will buy it again!!!! Perfect

The truth is that it seems effective. In order to understand how it works, I had to read the comments. It doesn't have any smell, but it keeps me dry and odor-free for at least 24 hours. I have no idea when it will finish or how I will know. I will probably start smelling again

If you are looking for something fragrance-free that provides protection for 10-12 hours, this does the job. Also, unlike the "regular" crystal, it did not cause any discomfort or redness, maybe the aloe helps.

Relatively difficult to use, you need to wet it to apply it. The positive thing about it is that it lasts a long time, but I don't think I will buy it again. It is also heavy, and if it falls, both the scent and the packaging will break. On the positive side, it doesn't cause irritations and it is completely odorless

It has a strong smell for me

For those idiots who say it has aluminum, antiperspirants that are ANTIPERSPIRANT contain ALUMINUM CHLOROHYDRATE which prevents pores from sweating. This specific one has AMMONIUM ALUM which is MINERAL and DOES NOT prevent sweating, on the contrary, it kills fungi like SALT. It resembles POTASSIUM ALUM (Alum block) which is also natural (references from ancient Egypt) and is used after shaving for rashes and cuts. Whether it was made in a lab or not doesn't matter. Diamonds are also made in labs but they are not toxic. The product works and doesn't leave marks. I hope the capital letters helped those who misinform the world. Whoever doesn't believe me can check the ingredients of Dove Classic which has aluminum to see the name of the ingredient.

An excellent product, eco-friendly, without dyes and chemicals. It should be applied well (with several circular motions) on clean armpits, slightly damp immediately after bathing, and the process should be repeated throughout the day as many times as each person deems necessary. Personally, after each use, I dry my armpits with a hairdryer. It goes without saying that it does not leave any stains on clothes when sweating. I consider its performance in intense physical activity to be close, although not as strong as widely available chemical products. I highly recommend it!

I have been using it for 2-3 years now and for me and my teenage daughter, it is the only thing that keeps us odor-free for hours.

I have been using it for about 2 months now and I can say that I didn't expect to like it. It definitely doesn't last as long as a regular commercial deodorant that claims to last for 48 hours. But it works fine for me during workouts and even on a cold winter day, I don't have any issues with sweat or bad odor. It doesn't smell like anything, neither fragrance nor sweat. Just nothing! That's exactly what I wanted because I don't like the smell in any deodorant. I don't know how it will perform in the summer, but I will give it a try. But for sure, I can wear it for 90% of my daily routine and when it's a special occasion, I can wear a regular deodorant for extra assurance. For everyday use, with daily showers, it's excellent and it doesn't irritate at all after shaving. The packaging lasts for many months! It's worth the money!

Excellent crystal deodorant. It takes about a week for the crystal to adjust to the pH in order to be effective, but afterwards, it really protects well against odors. The only negative, and for this reason it loses one star, is its packaging. I have bought around 10 of them and at some point they slip from my hands and break. I think the company should look into it

The best crystal ever!!! Ok, it's not super user-friendly, but for the job it does, I wouldn't change it for anything... they should do something to make it not break so easily....

The best thing I have ever tried in many years of using deodorant. I bought it in March 23 and September 23, and even though there was almost half left and a little more, it fell and the crystal broke, so I had to throw it away. Now I bought the Optima crystal that I found on sale, and it's twice the quantity.

P.S. It always needs clean, wet skin. If you apply it to a smelly armpit, obviously it will get dirty too

The best deodorant I have ever used.

Especially effective when I wet my armpits and not the crystal.

Because I read various comments after a small research, I present this excerpt from the first result on Google for the ingredient ammonium alum: "Yes, alum stones are a safe and effective natural deodorant. They're actually made of potassium alum which is different than the aluminum found in conventional deodorants, and they don't possess the same health risks".

Finally, obviously if we have already sweated and "stained", it doesn't work. It needs clean, washed skin.

P.S. A small downside is that the packaging doesn't close well and that it "cries" if it falls on the floor.

I had a serious problem with the chemical odors of supermarkets.... I finally sorted it out once I discovered this product. It does exactly what it says. Yes, it does make you sweat (after all, it's necessary for regulating body temperature), but your armpits don't smell at all, not even as a joke. Its durability is at least 24 hours

I bought it mainly because I was looking for something as "pure" as possible without aluminum, etc. It is particularly satisfying. Very good indeed!!! You wet it a little and apply it. It has no scent at all, it does not cause irritation, and once it dries, it feels like you haven't put anything on. No stains on clothes or anything. It does a very good job in terms of odor. Also, I don't think it reduces sweating significantly, but anyway it does not contain aluminum, so let's not expect everything. Another big PRO is that it is Value for money. Very economical and it already seems like it will last for a looooong time compared to classic deodorants that run out in about 3 months. A definite saving. If you are not put off by the product's uniqueness and the way it is applied, I recommend trying it and using it. Everything is a habit.

I have no particular issue with bad odor, but overall it has good results. Even a man I gave it to try, who had an issue with bad odor, had tremendous improvement! I consider it to be slightly better in terms of ingredients compared to what is available in the market that contain aluminum, etc.
