My second unit.the sound is good better than the others I have.Battery goes a round of golf walking easy.The course is way bumpy,even in a cart bouncing around.I just strap it to my bag and go.I have even driven off with the thing on the roof of the car.Probably came off at 20mph.NO DAMAGE WHATSOEVER.I didn't even scratch the solar panel.I did leave the plastic film on it though.Seems to charge fine with it on there.Anyway these things work bluetooth is good works fine with phone ipod whatever.
