Delivered in time and hour, super easy installation (two screws and that's it) Caution still not looking the ON-OFF button, there is none, use the small pin delivered with, insert the into the small hole beneath the illuminating face and push you feel a click and your light break forth like magic. As for the use, it is very simple as long as your solar charger is facing everything is done automatically, night operation exceed 9 hours full load !!!! The bluish-white light is more than enough to illuminate an area of 3m / 3m, it remains on standby all night and reinforced if someone approaches and there, the light is strong. Excellent product that works very well but that remains to be tested over time. I tell you: Nickel, chrome !!!!!
