I know the product is good because the cream form works well. The spray product is terrible. With both sprayers, I could not get the spray to work. I am not an idiot and I know how the sprays should work, but they don't. A product is no good if you can't get it out to use. It is awful. I will NEVER buy this product again unless they change the delivery system. NEVER!
