15 days I bought this article, everything works perfectly - very happy Put in a loggia to illuminate the night my comings and goings ... function: high-performance radar detection has all the moves, very satisfactory light power despite the small size of the lamp, and solar battery charging very well during the day and yet we had several days of greyness and rain that made me fear a failure ... but not at all !!! especially knowing that a small light remains continuously ON (pilot style).
