Rated 2 out of 5 by from gets the job done. too pricey for performance. pro: It works. Used this for the first time during some boat-in camping in. We were able to get quite a few radio stations; 2 or 3 came in clear. I was nice to have music on this trip. con: the unit fell about 2 ft to the ground with the antennae extended and was subsequently bent. now, the antennae can no longer be retracted fully. also, during the fall the back panel came off and batteries fell out during the small fall (thankfully the compartment tabs did not break). additionally, the speaker doesn't handle it's own volume capabilities with poor sound/sound breakdown early on in the volume range the the unit allows for. furthermore, I was never able to get the crank power to last longer than 20-30 seconds...i really tried; battery power all the way with this unit. I'm really disappointed and upset at these results. especially, given the price point the rugged appearance the unit has. I haven't read other reviews on this unit. if my experience is in the minority than perhaps i received a dud of a unit.
