I have a local store that sells them, and have thought many times about picking one up, but here's my dilemma.

Does the compass work inside the bag? And I literally mean 'inside' the bag.

Every time I pick up one of the kits, and roll it around, the compass points to some place different. (And not North).

Is this a sign that it is being affected by something in the kit itself, or has it somehow been destroyed in shipping?
