Without charging the rechargeable battery (NiMH) was only briefly from energy to light up the LED. The light disappoint some, because not yellow-white / warm white, but blue-white it was.
Even more disappointing, the guidance information that the ball for the initial charge must be made initially in the sun (and the almost sunless winter ...) so that the battery is fully charged. Again according to instructions well for 12 hours. Here, the switch to OFF (OFF) should be.
Next disappointment that this type of charging should be repeated every 3 months !! That makes no sense but, I mean, because the lamp according to Hotline only 5 hours lit when the battery is fully charged; thus the battery is totally empty but every morning, I guess. And in the FW 12 hours of sun?
As sites of the ball only full-sunny locations are correctly adapted, so largely without shadowing by trees, shrubs or building walls. Why then nevertheless once every 3 months to be charged in the sun to explain any of the case also required OFF position of the switch.
A replacement of the battery is very difficult, because after loosening the 6 small Befestigungsschräubchen the cover does not go down just like that from, because he is still held by silicon and certainly very well sealed. I have given up trying to pry the lid off in order not to damage but which the plastic. In addition, the lid in my opinion should be einsilikoniert again to ensure tightness. Much too expensive for an alternative envisaged frequent battery changes.
The earth spikes are actually very short. I give the balls 2 bought back. A great pity, because the balls with reasonable lighting would have made a fine decorative element in the garden with us.
From all: from me only 2 stars.
