I bought this microSD card from the amazon seller emartbuyuk. The item I received was fake. I confirmed it after calling SanDisk.
Things to look for when you check for originality:
1) Serial Number: The card I received had the serial number printed on the front. Original products have it printed on the back.
2) Packaging: My card did not come in the thermally sealed plastic package (the one that's really hard to open). Original products almost always come inside this.
I hope this saves people money and time.
