I bought this product so my 3 year old son could listen to music before going to sleep in his room. It is terrible. There is a constant hum as long as it is plugged in. The volume of the hum depends on how the power cord is angled at the back of the unit. The CD player never worked right. After a few songs there is a "ER" message on the screen. Most of the time I can't even get it to play a CD. I'm very disappointed. Don't buy this product.
