I suspect like most I was more than a little sceptical that a deodorant could truly work and last successfully for days. The scepticism didn’t last long. It was replaced with great excitement that I could go for a week before reapplying - and when it became (at this point) 13 days between applications there was a certain amount of awe. It is as good as - if not better than - they say it is and I’ll continue to use it for as long as it’s available. And buy it for presents for my family to try. It’s truly awesome stuff.
