I've had this speaker for less than a week and I think it's great!
It's small, feels solidly built and sounds really nice for something so small (it gets pretty loud too). I've had other portable speakers but they did not have Bluetooth - the fact that I don't have to mess with audio cables to hook it up is AMAZING!
I have used this speaker primarily with my iPhone - it's very useful for listening to Pandora when I go to places/friends' houses that don't have wireless internet.
I think this will also come in handy for road-trips and traveling. I might be buying a couple of these as Christmas gifts. :) (Posted on 11/20/12)
