I use this product before a big event - job interview, important meeting, social function - where I don't want to sweat through my clothing or will be wearing something sleeveless. It really does prevent me from sweating and keeps my underarms very dry! I don't use it daily because it seems that might be unhealthy (we sweat for a reason, right?) but for special occasions it is a lifesaver.

I have tried many antiperspirants and this does not work. Don't waste your time or money.

I have been using this product on and off for several years. It has never let me down. My husband and I both sweat a lot and this product works well for both of us, Recently my husband endured a day of preforming on camera under intense lights. He stayed dry all day. Buy it! You wont be dissatisfied. Be aware that it may be itchy the day after you first apply it.

USE THIS PRODUCT IF YOU CANNOT STOP YOUR PERSPIRATION. I had to stop wearing certain clothes because I'd ruin them or be completely embarrassed by the huge underarm sweat stains I'd have. Once I started using this, that all stopped. I don't even really use anything anymore, it's amazing. I'm down to using Certain-Dri 1x week or so and it's enough. This is truly a miracle product and I recommend it to everyone.

Finally I found a product that contains Aluminum Chloride. Until recently I had my antiperspirant sent from Germany because none of the products here contain it. They do make a stick version which I prefer but it doesn't contain Aluminum Chloride which I believe makes you stop sweating and there is absolutely no odor. On the box it says it's 72 hours protection and they're right, you really don't have to wash your pits for 3 days and still no smell (not that I've tried this lol). My only con is that it itches a little at first right after application but that's just me. Give it a try!

I love this product. It has helped me greatly with perspiration. My two biggest complaints is that since it's a roll on, it drips. And also since it is a roll on, it's hard to get just the "one to two passes" it calls for. I usually end up having to go about 5 or 6 passes, and therefore my risk of getting the burning sensation is higher. But even with that, I still love this product. I think it comes in a stick form, so I'll try that. I would so recommend this to anyone with perspiration problems.

I had high hopes after reading many good reviews. But this product does not work. Say your time and money.

I like that you don't have to apply this product every day!

Stuck to the directions. Haven't really had any BAD sweat attacks since I started using this. Great product. [...] Ordered a quantity of four which was probably too much considering a little bit goes a long way. Probably bought a lifetime supply. Oh well.

Okay some background , I am a 30 yr old male, and for as far back as I can remember i have had extremely excessive underarm sweating. Cold or hot weather, Running,Walking,Sitting ,watching T.V, no matter where I was or what I was doing, I would always sweat, that was before I used Certain-Dri! Wow! This product really works, At first I was skeptical; I tried every anti-perspirant imaginable , Nothing worked. I pretty much decided to come to the realization that I would have to wear either white or black shirts for the rest of my life(its harder to see the sweat stains). I decided to Give Certain Dri a chance, And I must say it worked! Now here is what I did when I first purchased the product, I showered the first night, applied the product,as directed, and in the morning showered again. I then put on the deodorant. That day I sweated just a little(for some reason I have always sweated heavier under my right arm). That night and the next morning I followed the same routine and viola! No sweat the next day or the day after! I have found the best way this product works for me is a 2 day on 2 day off approach although I have gone 3 days not using it and it has worked fine. I have been using this product now for 1 ½ yrs and its worked perfect for me in a hot N.Y summer last yr and I now use it all year. P.S for the Guys out there, I have found this product worked better for me when I trimmed my underarm hair just a bit Before use.
