Overwhelming response...units are used in schools, institutions for disabled,adults, and children, libraries, businesses, private homes, the list goes on and on. Anywhere that children have to wait. Now have a no mess indoor water unit and a no mess indoor art paint and craft studio. The unit can even be put on a white bedspread on a bed and when done playing the children walk away with no mess on them or in the area. Testimonials are great.
