PROS - I liked the idea, the children's lights and the pictures of the princess. It is very easy to connect a Bluetooth device. CONS - The volume control is very quiet on anything below "8". Children want the maximum volume of "10", and the sound quality deteriorates significantly. THE WORST IS THE LAG OF THE MICROPHONE. Your child or you cannot sing along with the song b/c delay. You destroyed my child's dreams. My three-year-old son tells me that "I can't sing". So I'm living the good life in a mansion when she could be the next Tee Swift.
