I have small kids so I do a lot of dishes. I hoped this would fit inside of all the sippy cups but the head is way too large. The brush is actually too large to fit into the curve of my glasses too. It works as expected on plates or other large items. I like that the brush head is replaceable and the soap dispenses at a reasonable rate unlike some others. Overall, I can’t use this on half of my dishes due to its size but it works well otherwise.
