Yeah, and about that same time this adapter came out, they roughly doubled the price of the 18 volt batteries, making it unrealistic to keep buying 18 volt batteries. The price of the adapter makes me want to keep using the 18 volt batteries, but the new price of the batteries makes me wish I had bought a few more before they increased the price. When switching to 20 volt batteries, you not only have to buy the adapter and batteries, but a new charger too. I'm not happy.
