Much better performance over my other, slower-speed (300X-800X), cards.

Great performance for 7DMII

The first two were 800 and they work perfectly in both the Canon 7D and 7DIII bought this 1066 for the 7DII as it has fast specs and reviews greater performance --- but I saw neither in comparison to the 800's

Great performance, simply the best CF a professional can get.

Greatly enhances the buffer performance of the camera.

Overall, awesome performance at an awesome price.

Because Lexar comes with photo recovery, I am attempting to recover the images that are as of now not-readable, but the cards will be returned once that attempt has been made

Works as it should.

They are dependable and work exactly as they are supposed to work.

Shooting in just RAW was super quick and I could blast away, as well as the 50 mp, no problem with rapid fire.
