So far very pleased. Received it in impressive time. Very well packaged. Great instruction. Have installed it and charged it. I love it so far but have not had the opportunity to use it very long. However so far very very pleased. Thanks.

Turned my river into rivermax. Love all the features and available power jacks. Really like the meter showing just how much juice the unit still has. Very high tech and cool looking digital panel.

Perfect for that little extra when you need it. Makes the unit a really good travel companion in the car or on the boat. Charged for free by the GA Sun is a win!
