Never buy Komputerbay cards even if they work with your camera! If you don't live in the US, then be aware that you do not have a warranty! They have the worst customer service I have ever experienced and treat their customers outside the US in an outrageously arrogant way!
Two years ago, I bought an expensive KB CF-card from Amazon. I used it just a few times with the 7D for photo and it died. KB claims that their cards have limited lifetime warranty but they never honour it, at least not for customers outside the US. First they said that the card was bought from an unauthorized dealer but when I provided all documents proving that it was bougth from an authorized dealer through Amazon in a perfectly legal way, they never sent me a RMA, explaining that they do not ship to addresses outside the US. When I gave them the US address of a friend of mine living in the US, with the request to send a replcement card to that address, they asked me to send the deffective card to them which I did, paying for the shipping cost by myself. Then they simply claimed that they never received it. Horrible!
NEVER AGAIN KOMPUTERBAY CARDS!
