I thought this might be of some interest following the thoughts my new Sandisk cards may be fake, so here are couple of photos that may help.
So the lower one is obviously the fake as I put a big cross on it, but if you look closely you can see the real one has an almost glitery ans textured surface whereas the lower one has a smooth plain surface. If you look at the printing, it is very crisp and well defined on the top whereas the fake is not clear and defined.
The above picture of the back shows quite an obvious difference between the two. the one on the left is the fake one. Sandisk don’t put the CE symbol on any of there cards, and they don’t make any of their cards in Taiwan. The card on the right is the real Sandisk, it has what looks like a label which is textured and shows a number and then MADE IN CHINA, which is where they are all made.
I hope this may help, unfortunately I dont have the packageing for the fake card, but all the print should be crisp and well defined. The print of the Etreme PRO in gold and embosed. The plastic holding the adapter and card has a peel of plastic film, some of the fakes are not like this.
