A lot of the normal deodorants in the market can last up to 72 hours but no pong doesn't seem to last that long. Is that because that the ingredients used in the long lasting ones have un natural ingredients? It doesn't seem to last very long after heavy exercise. Is that normal? Or am I not using enough or using to much? Does it make a difference? Other than that it's a great product. I love that it's all natural. Being a cancer survivor I don't like chemicals and unnatural products as already take a lot of medicines to stay alive. I am glad there is no aluminium in your product as they say this can cause cancer so that helps calm my mind. Thank you for your product it. You could say it saves lives!!
