It is extremely effective, meaning it prevents odor for at least two days for me, or until I sweat heavily. On the downside, I rank the packaging, and that's why I rate it 4 stars. As it is very small in size, it is difficult to hold when I use it. It would help if the base were bulkier for a better grip and therefore application.

I've been using it for a month due to pregnancy; I couldn't stand the smell of classic deodorants! It really does the job because I don't smell anything when I sweat, it doesn't leave stains or odors on clothes! However, in the last few days, it started to irritate me; I believe it's due to that because I've had laser treatment, so I'm not doing any hair removal...! I'll wait for my skin to calm down and give it another chance because it really is good! I'll come back with an update!

I didn't expect it to be so effective. For me, it has the same duration as the roll-on deodorant (which anyway didn't keep me fresh for the whole 24 hours, especially in the heat). However, it has the following advantage: it doesn't leave that slimy feeling that deodorant does. It's essential to apply it right after the shower, and if a reapplication is needed, to wash the armpits again.

It is not against bad odor. As soon as you sweat, you start to smell. It does not cause irritations and does not leave marks. But it is not for bad odor.

No irritation on the skin, even when used after shaving. Completely odorless and provides 24-hour protection. Lasts for over 6 months depending on usage.
