Last stick purchased was hard as a rock and unusable [SEP] This stinks, literally. I have purchased this deodorant stick 5 or 6 times on the past and am a huge fan, but something changed with the formula. I bought another stick at the same time from a different, non Amazon seller and had the same issue, so this is clearly a brand issue. Anyway, in the past I have been able to push the stick up in the carton and had a smooth application, but this stick was hard as a rock and would not move, even after trying to warm it up. I have since gone back to the jar as opposed to the stick, which is just as good as always.
