Summary: I love Bose speakers and bought this speaker and the Bose soundlink mobile bluetooth speaker (costco item # 669000) for my son, who is in active duty and needs to be lightweight when traveling. He tested them both and says the 669000 is much better, has truly amazing sound at half the weight and half the price. So do the math, Bose is always good but bigger is not always better.
Summary: The sound quality is outstanding. A downside is that the adaptor on the front of the unit does not accept new iPods and the iPhone 5 so you will need to buy a Lightning to 30-pin adaptor ($29) if you have the newest models. Another downside is that there are no volume controls on the top of the unit like my old SoundDock so you have to use the suppied remote.
