I purchased these so we could add some fun dimension to our wooden fence. These installed easily, one screw each, and they create such a fun design on the fence, while lighting up the path or fence line. These worked immediatey out of the box, all I had to do was turn them on. They charge with no trouble and at night we look out and see the fun artwork. Very happy with this purchase and these dolar lights have added some fun decor to our backyard.
