I am so excited about this product, so far. I will HAVE to update this review as I am just now in the process of trying the product out. Why am I so excited? BECAUSE I CAN ACTUALLY SMELL THE PRODUCT WORKING!!!! I know you think all products smell but this smell is not the smell of the product. It is the smell out the interaction of this product with the urine. They tell you this will happen and that you open a window and let the fumes out. IT is safe but for comfort for the nose you will wan to do this. My husband and I do rescue work. Needless to say, accidents happen. We have spent a small, no...quite a big fortune...trying to find a product that truly works. I think and truly believe I have hit on it. I do not want a perfumed product..I want one that eliminates the problem. I will come back and update once we use the product enough to KNOW my expectations are met. However I am hopeful this product will be the answer! Either way you will be hearing from me again soon and I will tell it like it is...that is a promise. I got a coupon on FB that gave me $20.00 off my first purchase. It did ask for a review. This will no way affect the honesty of my review. I am so very hopeful this product will exceed my expectations. I will let you know. :)
