Frustrated with Advanced Build & Sons Niigata's lack of response

I'm adding this comment to provide additional information. The wireless speaker from Advanced Build & Sons Niigata not only failed to work as advertised but also damaged my other equipment when I tried to use it as directed in the manual.
