I purchased these lights as I had some experience with solar lights before and wanted to try these. These came packaged very well in a box and are of very good quality. The glass beads seem robust and can probably handle the rough weather conditions, although the length of the lights is not that much. They turn on automatically when there is no Sun and turn off when the sun comes up. My lights started to give me problems after a month of usage but Hardoll was kind enough to send me a new set of battery for the lights.Its a bit expensive if you consider the other plug type rice lights but you would be spared of the hassle to put them near a plug point. These work fine unless and until you place the solar unit under direct sunlight.Overall a nice addition to the garden.
