I bought a Wiikey SD Adapter recently. The damn thing got stuck in my Wii. I had to yank it out. Which bent the springs inside the Wii the wrong way. Luckily I managed to push them back down. The problem comes from that the Wiikey SD Adapter has a lip which gets stuck on the springs. I've found that breaking off the that whole lip area, still allows it to fit fine into the Wii. Still need to get Swiss working to know if it works though! Thankfully I do know that normal GC mem cards do still work in that port! Just thought I'd give out a warning though!
