I rarely give a 5 star review of anything, but this really was a surprise. I bought it as a gag gift as a family present. I saw the reviews about it not dancing, but I took a chance anyway. The sound is better than good given its size, the battery life is more than adequate, and it’s relatively inexpensive. Those that are saying it doesn’t dance the way it should need to read the directions. There is a button on the front that turns the dancing feature off. It “coos” when it connects to bluetooth but then you have to make sure its set to dance. It really is worth every penny, if nothing more, as a small speaker to keep a toddler or older infant engaged.
