SAME thing as EVERYONE else has to say! This is the 2nd mobile we're going to exchange. Don't get me wrong, my daughter LOVES it but all of a sudden we go to replace the batteries and it stops working...we put 2 sets of batteries in so we know it wasn't that. BIG LET down. The music is great as well as the shapes and colors. Everything about it she loves, but boy will she be disappointed when she realizes that it doesnt even work. For $40, you'd think TINY LOVE would make a better product.
