I bought this as it's low fragrance and I prefer deodorants that have a minimum of a scent, particularly if its a floral scent. It's also cheap (less than $5, not $15) and often on special too.
I'm not sure how this is hypo-allergenic, though it is low fragrance and low alcohol. I don't have sensitive skin so I cannot comment on that aspect.
This has a light fragrance and kept my dry - all I ask really. I prefer roll ons to spray deodorants as I find them more effective and less likely to get up my nose and in my eyes.
I might buy it again, but I have found others with a better applicator that I prefer more.
Personally this product is not for me as I didn't enjoy the smell of it and I found it didn't do as well as a job as other products I have used in the past. It also left white marks on my clothes. Not a huge fan
