These actually light up as soon as they hit the water. Just add flowers or novelties for a cute display. Great for kids.
We floated these in our pool inside of plastic wreaths for an event we hosted and they looked absolutely beautiful. Not a single one (out of 30) malfunctioned or ran out of battery. I could have sold boxes of them that night!
I have recently purchased it. Seems to be good in quality and works well.
So easy to use. Just perfect
