Simple device, working as expected, using them in layered garden on a small hill. There is no installation involved other than turning two butterfly screws to adjust the angles of the solar panel and the light. A little more brightness without diminishing the amount of time it stays on would have been nice but overall I like the product. I had purchased a couple 2-3 years ago and they are still working. During the winter, I keep them indoors/do not use them.
