Bought this because a $5 off coupon came in the mail. Sounded good. Costs approx. $30 in the drug store. Find it in the medical aisle. Have used for approx. 3 weeks every morning. No discernable difference. There is a guarantee, however I was not aware of this and threw out my receipt. If you choose to purchase, I recommend that you keep your receipt and send back if you do not see results in four weeks.
