Review on Chunace 2 Pack Rechargeable Toilet Night Lights - 16 Color Changing LED Bowl Nightlights with Motion Sensor. Perfect Fun Novelty Gadget for Him, Guy, Men, Boys, Toddlers, Moms, Brothers! by Nathan Theriault

Also thought it was a night light outside the toilet but it's not. The sensor does not always detect movements and when you press the button; it should iterate over all colors. If you hold it to the color you want, it should stop at that color. I bought 2 packs and one didn't stop at any color so I had to put it away as it kept changing colors. The other one chose the wrong color and now it doesn't change, so I'm sticking with that color. The colors aren't as vivid as I'd like and I wish they were rechargeable, but that requires batteries. I bought new ones to replace them but haven't used them yet. I hope this new brand is better so we'll see.
