I bought this Wii Balance Board in it's original box, used at Goodwill. The battery terminals were all corroded but luckily the electronics board looked good. I made the video to show how easy some things are to disassemble and address, even though they involve some masterful tech. This was an impromptu video done on my phone so hopefully it's clear enough to get it's point across even though I began the video about halfway through when I was basically ready to reassemble it. Thanks for watching and "HAVE A GOOD DAY!".
