Summary: These cards come with built in write protection. If you have a problem with the card, you cannot simply reformat the card. You have to buy the Transcend card reader in order to reformat the card.
Summary: Bought this for my Canon 30D. Had good reviews, well, don't believe them. I can only assume that quality of these cards is getting worse because they aren't used as often. EXCEPT very nice high end cameras that are workhorses still use them, Many high end Printers use them as firmware boot cards.
Pros: Took about 30 pictures. Got some of them off before problems
Cons: Died after taking about 30 pictures... Got "Err CF" in the middle of taking a picture. Now I can't retrieve the ones I hadn't already copied and can't format the card in computer OR Camera

20 February 2013
Summary: This was exactly what I needed for my Cannon DSLR! It's a great deal for the 8GB card. It will hold so many photos which is nice because I don't download as often as I should. Very happy with this purchase.
