* Depending on the metal battery clip style and plastic thickness, the battery positive terminal may not make good contact, without carving some of the plastic away with a knife.

Assuming 2 AA batteries would need to be replaced in a device each year, this design pays for itself in just over 2 years time. If an environmental cost is factored into the production/disposal of Alkaline AA's, the payoff time is shorter.
