Review on 📷 Lexar Professional 1066x 64GB (2-Pack) CompactFlash Card, Up to 160MB/s Read, Ideal for Professional Photographers, Videographers, and Enthusiasts (LCF64GCRBNA10662) by Sivabala Mickel

It could be a fake. One is used in the Canon 5D Mark IV and the other is used in the Canon 7D Mark II. Both cameras showed the recording as usual. When trying to read the cards, I just get a "Card not read" error message from a MacBook Pro. When I plug it back into the cameras I get an error saying there is no card. There is no way to reformat and reboot. So I lost the photoshoot and both cards are completely useless. I bought them in a pack of two from Revain three months ago. I've never had a problem with Lexar and have many of their cards. So I'm suspicious of them. Carefully!
