This radio is very compact and holds a charge very well so far. I purchased it primarily as a weather radio and for emergency use. The weather radio works very well. I have not used the two way marine radio as it is my understanding you have to be on the water in a watercraft or on the dock/shore to legally use marine band radios, but it is doing what I purchased it for. Price was good. Seems to be very well constructed and I have had good experiences with other Cobra products so I expect this to last for many years.
