"It does what it says on the box and have seen some improvement, yes it only works when solar panel is in direct sunlight and does not retain any charge (like solar garden lights will), but with this warm weather it has been a great help to fish.
The negative has to be that you must not walk infront of panel or it stops, pass across it for a second and it stops. So cross between it and the sun and you have to move it to a fresh location and it's starts again. So very temperamental"
