I bought this at a garage sale for a dollar (less than a year old), and it worked for a couple of months. I replaced the batteries, and it still didn't work. I decided I had nothing to lose by taking it apart to see if I could fix it. When I did, I realized it was far from water tight, and the electronics in it could easily get wet, even when using the unit properly. There was no reason for the holes in it (besides the speaker holes), and really no way to keep the electronics from getting wet. I tinkered with it and still wasn't able to get it to work. While it worked, it was fun and had a cute song, but it should be built for the bathtub since it is a bath toy. I'm glad I only spent a dollar. Save your money, and use the radio or a CD!
