I ordered one set of these to see what they would be like, as I wanted to run lighting around my swimming pool. After the first evening, I ordered three more sets. Easy to install, and maintenance is non existant. Just enough vibrant blue light to trace the edge of my pool so people can see where it is, but also just enough ambiance to make it nice. No cords, no wires and no electricity.

Worked well for the first month then started to work now and then
changing battery did not help not working at all now tried changing
battery and direction of solar panel still not working.

When we received the lights we were happy to discover the solar collectors were small and easy to install on the balcony railing and took up little space. Although the collectors are small in size, the lights remained lit late into the night.
My husband & I recommend this product for ambiance enhancing settings where just a little extra lighting is desired.

Layed it around the bottom of the circular pool. No wires to install and no danger from splashing water.
