Purchased two of these from ebay they are the zoomable 5 mode ultrafire brand flashlights takes 2 18650 batteries, I have six batteries I’ve tried in these (batteries work) and neither flashlight will turn on and never have. I’ve contacted the seller no reply yet anything I can do to try and fix this issue? All the parts seem to be tight and have good connection I’m not 100% sure though.
