It is easy to use, Just put it into the container with water and whatever kind of cleaning product you like. I plug it in although it has a battery option,
It cleans . You empty the container of the liquid and rinse it out.
I feel my mouth guards are cleaner, but since I got this after having mouth guards for ten years and hand cleaning, my mouth guards still have residue.
But less . Maybe over time , it will all be gone
