... The package finally arrived after a month. shipped from China in a small bubble envelope. course were 2 pcs. during delivery already defective. the first light I then used, has shined exactly 2 seconds.. thus was already no. 3 broken. So there are still 7 of 10 pcs. left. No. 4 lit goodness thanks since about 5min. mind you with no problems! but we are honest, for the price I would not even get upset when the bubble envelope had arrived without content :)
