I've tried many other deodorants which claim to be fail-safe but none has ever compared to Blue Grass. It's more expensive than I would like and is becoming more & more difficult to find (not available on the hight street or online in the UK). But I will continue to buy it so long as it's available unless the cost becomes unmanageable.
It has the most beautiful, clean, fresh fragrance and has always proved 100% reliable.
