Good? I dunno.... It's adequate, but then maybe my application was a little peculiar. I bought two adapters to fit insoder a U. S. Navy battle lantern so I could power the lantern with eight D cells. On one side of the lantern, the adapter slid right in, just fine. It has these extension legs or fins sticking out the bottom that slide correctly into place on that side of the battle lantern. ON THE OTHER SIDE, HOWEVER, I had to take a blade and cut off half of one of the extension legs and trim the opposite support gusset. It fits fine, now, but I have no idea why the same adapter won't work on both sides of the battle lantern. Regardless, since I'm using rechargeable Li-ion D cells, I now have a rechargeable battle lantern, made possible by these adapters. Pretty cool, I think.

perfect for what you need it for. Sometimes finding a lantern battery is hard to do in my area, this makes it a lot better and easier. "D" batteries are easy to come by. Works great!

I purchased "D" rechargeable batteries. I will save so much money overtime. Those 6 volt alkaline batteries are expensive. The best thing I have bought.

Use in game feeders and they work great, a lot better than 6 volt battery, but hard to find.
