UPDATE: 6/22/20. The seller contacted me after my review and received a full refund. They informed me that they are very sorry about the issue and are looking into the issue. The seller continued to message to ensure my refund was processed. Although I received a card that didn't work, the customer service was excellent! I, like many others, took the risk of using this memory card only to ALSO end up with a corrupted card! Very disappointed I waited to play some of the GameCube games we play with my son only to be let down by a corrupted memory card. DO NOT BUY EVERYTHING CORRECTLY, THIS IS A DAMAGED MEMORY CARD! Frustrated that I have to spend time returning and buying a differential to play with my son.
