I spent about 18 months trying dozens of alternatives to big brand deodorants, and Scully's was the clear winner. I've been using it now for a few years, every day, on my armpits, under my breasts, and down under - I live in the swampy South. Thoroughly delighted with the way it works, and it's the only deodorant that doesn't irritate my skin.
The only reason I'm not 100% delighted with Scully's is the cost: $24 for 9 oz is a lot, and I'm just not used to spending over $100/year on deodorant. I wait and buy it on sale, though 15% off and BOGO 25% off aren't great deals.
For now - worth it! But if we tip into a recession, this might be one of the "luxury" items on my shopping list that I'll have to replace with a less expense option.
