Customer feedback reports perceived effectiveness and easy application, including favorable reports of continued use. Experiences with residue vary, with some describing it as non-greasy and others reporting an oily finish. Value opinions are also mixed. The monthly topical format may suit buyers comfortable with repeated applications, but residue concerns could matter when applying it around a dog's coat or home.
