I’ve been using it for about 6 months and I love it, not had any issues and it lasts ages and works well. However I generally have rhinoceros hide rather than skin. My husband tried about 5 different natural deodorants and got irritated by all of them until he found the Mitchum natural bamboo one - only problem is it doesn’t last long.Just wanted to say that I bought that Wild deodorant because I was wanting something less wasteful than normal plastic deodorants and I now have a bright red rash all over my underarms so won't be able to use it anymore despite it being really expensive
