I think these look so beautiful in my pool at night and are the best product idea for outdoor decoration in the water! I had a great experience last year with them. I packed them up for the winter, but I advise that you make sure after you deflate, you hold the power button down a few seconds to shut the solar power charger down. 2 balls did not work this year, and the owner was terrific in replacing them and helping me via text. I have learned that many of the initial issues starting up are that it needs to be powered on to charge. The instructions say to blow it up first, but my advice is to press and hold the button on the moon for a few seconds, release it, then blow it up and let it stand in the sun for the day. After it's charged, you can adjust the kind of lighting you want by pressing the button quickly at night, so you can see what you are doing. If you live in a seasonal climate where you pack away for the winter, you can expect two seasons out of it. Worth it to me.
