Query: BEWARE Electrical Issues

On my second speaker and about to take this one back as well. As others have commented the on-off switch is a problem. It worked fine (although the sound is poor) at first but then I couldn't get it to turn on. The second speaker would not turn off. I unplugged it so it wouldn't run all night and found that it would not turn on again. That on/off switch is defective. STAY AWAY
