Query: Don't buy this product

This product is no different from all the many scam products that exist on the market. Firstly, the smell is horrible, so unless you intend to hold your breath while making love, forget about it. Secondly, the only sensation my wife and I experienced was a burning one, thank God we did not use an entire package. And for those of you who don't like having your credit card debited without your permission, I strongly advise against doing any transactions on the Zestra.com website. Even if you choose the 'free' sample, you will still receive monthly shipments, at your own expense, without your approval. They simply send you an email notifying you that they just billed your credit card etc.The last bit made me certain that this product is nothing but another scam, running its course. So buyers beware.P.S. They only got one star because Amazon doesn't allow you to give less.
