Summary: First of all I live in the Caribbean so I received the speaker dock couple weeks after it was delivered in the US. Then the speaker refused to work and the remote had pieces missing at the back. I emailed the seller and said that it was not working and pieces were missing and he/she was not cooperating. I AM VERY DISAPPOINTED. AMAZON AND THE SELLER SHOULD BE ASHAMED.
Summary: Good sound. We use this in our kitchen to listen while we cook, so the volume is never really loud. I like Bose products and typically buy name-brand quality products - this is one of those products. . . I recommend the plug in 110 volt variety. It's much cheaper and I've heard the battery Bose doesn't have as much power for the speakers. We like ours. . .
