Over the past few months I have tried various natural/unscented deodorants (ie. Mitchum's Unscented, Tom's of Maine Unscented) and the crystal rock version is by far the best deodorant I've ever used. Even on my sensitive skin it works wonderfully, just be sure to wet the rock very well before application. There is a slight salty smell to the rock, but it works wonders once on my body. I scored high on the price since I believe this rock will be lasting me a very long time. Highly recommended!
