Great product!
I used it on my Wii to play some GameCube games, and it works perfectly fine! A lot of extra storage too, unlike the standard 59 blocks memory card, this one has massive storage!!

GOOD!!!!
best product works perfect

Not the good product received
I ordered this card because it was a DATEL, but I received a Noname card, called "Massive Memory 128" bundled with a homebrew GameCube compilation disc (craps games, really).

This card is not working at all.
you can copy your saved data from another memorycard to this one. the data will be read correctly in game.
But if you want to save your game on this card, it will only create the Game Block on the memory card but the data will not be written, or will be corrupted.

I tried many games, some games said "saved", but it really isn't. Just reboot and see no record at all where saved. (Mario kart)
Some game said "corrupted data" and just save randomly (Pikmin)
Some other game just ask for an "Official Memory card" and say the save might not have work (Mario sunshine)
And finaly some game just ask you to format you memory card as it is not readable (Fzero GX).
After formating, it's still not working.

This Noname card I received is really a piece of Junk.
I asked for a Datel, and received something really bad and not working.

Good!
Even it's not official Nintendo accessory, it's BIG! Works just fine on my cube. Quality memory card, and cheap too.

Just got my card
Well I just got my card... Actually it shipped on the 19th of october, arrived in the Philippines by november 8, the post office sent me a notice and I recieved it on november 10, and I dropped by the post office today and got it...

I moved all my old game save into this card and I've got really really lots of blocks left over
