Great sound and battery life...

Love this speaker.  Let a friend take it for the weekend and was unable to truly test the solar charging ability.  Even if that does not work, this is a great sounding speaker.  Does not hit the base hard and is not too tweeny on the highs.  Provides a nice balance.  Should probably be used in small venues as it does not get terribly load.  Tried it on a street corner during a running event and with the road noise we had probably a 20 feet of decent hearing ability.  I would have no problem suggestion this to a friend.
