The actual items themselves are pretty neat, but the fact that they are all artlessly dumped on your character means this DLC will actively make Fallout: New Vegas worse without something that makes the integration of these items into the game more elegant, such as the JSawyer mod.
At its best, adds an annoying message that appears every ten minutes. At its worst, breaks the early game with a bunch of random weapons, then becomes completely useless as soon as you get something else.
