Although I can't tell if it's actually killing germs it seems to do what it's suppose to. I mounted it on the bathroom wall and it can accomodate any type of toothbrush we have including strange sized character brushes for the kids. It turns on when you close the door and it does periodically turn on after the initial cleaning cycle. Maybe it's just that the weather is getting warmer or a coincidence but we do seem to be getting sick less since we started using this.
