It works for about a week (for a guy) [SEP] Hmm. Let me start off by saying that I am a guy in late 30's, and maybe this deodorant was designed primarily for women.... but in my case it worked for the first week or so, meaning that it would eliminate armpit odors nicely (BO) but then it started failing at about 3 PM or even earlier in the day. And I mean, really failing. I'd smell like I just ran a marathon and then sat in my office for an hour -- that bad. Also keep in mind that this product can really stain your dark shirt if it comes in contact with your armpit. It leaves those nasty white marks (that can be washed off, but still a nuisance if you're on a run in the morning.)<br /><br />So my verdict -- this product is not for me... sorry.
