I am a 61 year old woman who has been using these Jokari Whale Faucet fountains on my bathroom faucet for probably 20 years. Just perfect for rinsing after brushing my teeth, rinsing my face and ears after washing them, and for wetting/rinsing my hair after washing it. Never want to be w/o them so just bought another 3-pack. The plastic does get hard after about a year or two and even though they are still usable and work fine, they do tend to easily fall off the faucet after the plastic dries out. You don't have to have children to use these; they are fabulous for adults, too!
Great. Exactly what I wanted.
