I just received my new shorter body 5v GLV and it rocks.The issues I had with my red prototype are not present in this version.The batteries are still snug but not tight in the tube.Even my trustfire 3.7v protected batts slide right in.The shorter body is a direct result of a shorter spring and makes install and removal much smoother than the old style.The new style GLV-looks good,feels good and works every time.What else could you want?
