Review on KOMPUTERBAY 64GB Pro CF Card - 1000X Speed, 150MB/s, UDMA 7, RAW 64 GB by Karl Swift

I was very happy with it, especially the price compared to GB was very attractive. I have a 5D Mark III and bought this card to shoot on the go but it either freezes or won't save files. After a day of shooting I tried to upload and all I got was BLACK! Very frustrating... made a few more attempts and the same thing continued, either frozen, black frames, or it prompted me to remove and reinsert the card and even format the card every few attempts. When I contacted the seller they wanted to know EVERYTHING from my camera to my computer (it's a MacBook Pro I got a few months ago). The bottom line is that it's VERY difficult to fix and at this point I'll just throw it out…. because it is a big problem for me!
