The Water Dance Portable Bluetooth Speaker is a great portable speaker it's has a great sound to it, and as the the water dances to the beat with the color lights it's a over all a great experience. The water dances with the color lights depending on the different music it is playing ,which is really cool because it changes the patterns of the water by beats of the music. I really like to turn Water Dance Portable Bluetooth Speaker on in a dark room and jam because it gives off a light show on the ceiling.How it works is their a USB charger and you charge it up first. It charges really quickly by the way. Then their is a switch on the back of the Water Dance Portable Bluetooth Speaker, that you switch to on and it will connect to your Bluetooth and away you go to listen to your tunes and jam a way. It can it also be connected with auxiliary cables, or it can be used wireless, it also can be connected by USB to your computer .It's also has a nice design so I can leave it out and not have to worry about hiding it. I believe anyone who likes to listen music, would love this item. Because the sound quality is excellent and I also think it would be a great gift idea for anyone and especially children they would love this during the day times and night times. At night time I would suggest maybe getting educational or fun audio books at night while the water dances and colorful lights would be a great night light for the kids to fall asleep to. It didn't come with instructions, but it was pretty easy to figure it lets you know when the Bluetooth is connected. All in all a great find.
