This is great…except for some reason the light sensor doesn’t recognize when the light in my bathroom is on, so the light doesn’t turn off automatically like it should. BUT, when I turn on the light in the room right next to my bathroom, it does turn off. It’s so strange! I had to knock a few stars off for that because it’s going to end up draining the batteries (3 AAA) much faster than it should, which is a bummer. Other than that this is pretty cool and useful (and fun) if you have kids that get up to go potty in the middle of the night all the time like I do.
