Query: BoomBox purchase review

I had a BoomBox that finally conked out on me, that's what prompted me to purchase a new one hoping to get one exactly like the one I had. So I was very disappointed, when I found that it did not have an on/off button. In order to shut it off it is necessary to unplug the Box. If I would have known it did not have an on/off button I would not have purchased it. It came from China, so they must have different codes than we have. Another convenience my other Box had was that I could hook up multple speakers to it. This one has only two plug-ins for its 2 speakers. I could not discern from the photos whether these features were there. I am not mad at Amazon.com, because China is the one that messed up. Are there any electrical devices built in the USA, that do not have an on/off button or switch?
