I have been using this product for 4 years now. I usually buy small bottles, especially for cruises, and they do a great job of removing odors in the bathroom. A year ago decided to buy refills and save some money, "WRONG"! These dressings are made up of 99% water and about 1% essential oils. I lost about $60 thinking I was saving. I usually accept losses, lick my wounds, and don't say negative things about sellers or products, but I understand that other people can lose a significant amount of money too. Do not buy this item from this seller as it has been tampered with.
