Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I use these for travel and for home use. I do not have kids. I love them because planes/remotes etc are dirty in travel situations. use these little things to get them clean. I figure if they can clean a babies butt then they clean other poopicles off hard surfaces.
