I ordered four flashlights and it took about 3 weeks until they were there. When I tried out the flashlights with 1.5V AA Batterrien came the rude awakening, they did not go. The described trick with two Batterrien and a paper clip I took them to light up, but I wanted to purchase any 14500 batteries because the flashlights were provided partly as a gift. There are, of course, not 5 star. I immediately contacted the seller and described my problem. He spoke German and was very friendly. He immediately sent me 4 flashlights that work with 1.5 AA batteries. He also said that in future all flashlights also support 1.5V AA batteries. The flashlights even I find really good for the price. For dealing with the reported problem and the value for money I forgive 5 Stars.
