Awful!

I tend to alternate the brand of deodorant I use, as I find them more effective that way - I need a good, effective deodorant due to a busy job.
I tried this one thinking it would do what it said, but sadly within a couple of hours of using it, I could tell it wasn’t working AT ALL!!
It’s expensive, which would be fine if it worked, but I wouldn’t suggest anyone waste their money on it
