Revolution 2 Universal Controller Charger Review

At our house, a mission to complete Lego Star Wars III: The Clone Wars on the Wii has been undertaken by my son and me, with assistance from my daughter (Mom's not so into it).  As you might imagine, this tends to drain a lot of Wii controller batteries.  Rather than waste a small fortune buying standard batteries, I've started to convert to rechargeable battery packs and chargers, like the Revolution 2 Universal Controller Charger by LevelUp.  Let's have a look.
