Great Buy

I ordered two UltraFire batteries for my flashlight. Order came very fast and the batteries were exact size I ordered. The batteries came with two flashlights. Tried the batteries in my flashlight and they work great with plenty of power. The flashlights that came with the batteries were very nice and throws a great light.
