I have tried a few natural deodorants and woohoo's Wild Extra Strength is certainly up there with it's ability to reduce any odours.
It is easy to use, compact to put in a handbag and doesn't melt on hot days.
It works for me, but it does feel more moisturised / greasy than other brands I have used. Which isn't necessarily a bad thing, I just wasn't used to that. And it is because it uses such great natural, healthy ingredients that it feels that way.
And I had all the proof I needed this weekend when I went on a 6km hike in the hills on a really hot day, and I was the best smelling person in the car at the end! (Yes, including people wearing strong aluminium based antiperspirant deoderants)
