I purchased this product back in December 2011 and it worked great! I took it everywhere with me, hotels, beach, you name it...I was in love with this thing. Around June it suddenly stopped working with my iPhone 4s. I took it to the Apple store and none of their units worked with the 4s any longer either. I believe a firmware update is much need otherwise you're just buying a table stand. They apple store I took mine to actually took all their products off the shelf.
Great, compact, powerful, travel product except for the horribly big power adapter. Speaker component itself is fantastic. Incredibly full sound, including low end, for such a compact unit. It's chargeable, so it'd be great to take on outings where there isn't a power source. But, if you plan to use for extended travel and use in hotels like I am be prepared to lug along the god-awful power adapter. The cord is fairly short also. Definitely a head scratcher in contrast to the speaker itself, but not a deal-breaker. I think I will enjoy this product.
