Worked great for about two months for 11yo son with Herbst expander. Impossible to floss manually so the water flosser was perfect. We were happy with it, then on it's first trip it fails. Charges fine, motor does not turn on so it's a paperweight. Outside the returns window so leaving a troubled review is the only thing we can do.
