They are easy to use and look interestingly different. The blob of liquid soap is just right. Somebody gave careful thought to how to use them by operating them with the back of your hand – quirky AND clever. It's the palms of hands that need most of the washing. We did have one of them reluctant to work, initially – then in the efforts to get it to squirt soap, I tipped it upside down, heard a bubbly, gluggy sound, put it right side up and all was go. Seems fine now.
