I'm actually using this product in my classroom. It was easy to hang up in a convenient place, which is not always the case with items, is definitely water resistant, which was obvious after me spilling water on the button the first day, and the volume control is perfect. I can adjust as need be in the classroom. This is the perfect item for any teacher who wants a constructive, effective way to get students to refocus or quiet down without having to nag.
