This is a nice accessory to have, if you already own a DeWalt battery pack and the charger.  Basically, that would limit my recommendation of this product to those who already own a cordless 14.4 volt DeWalt tool.  While the flashlight itself is relatively inexpensive at about $25, the battery pack and the charger are not.  The battery pack cost more than $50 apiece.  Add the cost of the charger and you get the idea that this is not a flashlight system that you buy on its own.  But, if you already own the battery packs and the charger, then spending an additional $25 will get you a very powerful and durable flashlight.
