The product would work great if you have fresh batteries, otherwise the static takes over. I have lost my AC power adaptor for the speaker and was unable to find a replacement to fit the jacks on the speaker. When I called the company to inquire about purchasing a new AC adaptor I was told that there are no parts manufactured that could be bought separately. In other words, if I need an AC adaptor I should purchase another speaker. Great business making definition!
