The product does its job. Unfortunately, the manual is very meager and inadequate. Some displays and symbols are not explained. The programming (at dusk - midnight again - in the morning and then again at sunrise from early again) the switching times, but not described is allegedly possible. In many experiments, the light then remained in the daytime, rather than to go out at sunrise again. A search on the web for more detailed instructions were unsuccessful. I wonder how functions are touted in the product information, the documentation is missing. For people with a lot of expertise and patience a useful product!
