Works Pretty Good
I have NiMH AA batteries and they work fine with the adapter on items that require D batteries. The only problem I encountered was with a flashlight that had a wide contact spring at the negative end of the battery and did not make contact with the smaller AA battery end. There are other adapters that have a solid piece of metal on the negative end. I would only need one of those adapters to solve my flashlight contact problem, but the reviews on those adapters were not so good
