I purchased a Nasal spray that was on sale called Sinus Buster. I brought the product home and used it with the most horrible experience I have ever endured!! This spray is derived from a red hot pepper extract and other natural ingredients, the experience I had was like shooting pepper spray up your nose!!! I work in Security and know what being hit with pepper spray feels like!! My sinuses were on FIRE, my eyes were WATERING. and my breathing was LABORED!!! These are all the same reactions you get when exposed to pepper spray, this is not a product that I would even recommend to MY WORST ENEMIES!!! On a scale of 1 to 10 this product rates -10!!! read full review »
