I thought this was the dumbest thing until I had one. Now I have one in every toilet.

I have these too. They are motion activated night lights for the toilet bowl, so you can leave the bathroom lights off at night and save your eyes, as your destination lights up to greet you. It's fantastic.
Thatβs just gross to put some unnecessary crap in/at the bowl. Just have a normal sensor light anywhere else in the bathroom.
