The first time I went out for the night with no backup battery just the ego and did not worry one bit was great.Resting it on its end makes for a standing salute to the greatness of the ego, and its hard to lose too.Great purchase and reward for little money upgrade over the regular 510.Have you already found a smoking victim to show the vaperlight to with your old 510? That will come around the corner in a months time.Enjoy ,the day I got mine is still one of the best days of the year so far in vaperland.
