The device is absolutely OK ... But, the accompanying description was for garden solar lamps on a stalk to put in the earth; plus very long and in English (no "easy school English") .. I have to think a little more than required and have the "on switch" so quite by accident found, because I have only not dare to open the device (for the guarantee, although it should be). Too bad, because the lamp is otherwise highly recommended. By the way, which was intended as a gift and was very well received, works flawlessly.
