Works on Nikon D850
CF-Express is still relatively new and also relatively unused memory card so it's still VERY expensive memory, so you have to decide if you want the really fast write speed in camera, and really fast read speed when you want to copy it to the PC to edit the photos. Or use the cheaper not CF-Express memory. I decided to go for the speed for sports / wildlife photos, and despite it not officially being designed for the Nikon D850 (you may need to update the firmware if a D850) the memory is amazingly fast even in burst mode, and when copying to the PC the copy is also very fast, but you'll need a new CF-Express card reader to benefit from the speed. The only thing to note is due to its speed, this card gets really quite hot and quite quickly when copying files to the PC. Overall, I don't think you'll regret this card.

Too expensive, but blazing speeds.
After spending hours researching these cards for my new Canon R5, this came out on top as the best for speed, reliability and value for money. Compared to the other options, this is definitely the best pick. It’s faster than everything else at the price point.The reason for the drop in one star has nothing against this item in particular, but the fact that these new CF cards are wildly expensive. I hope that the prices decrease in due course as they become too popular.I wouldn’t advise using these unless you’re pro, just go for a fast SD card instead if not and save the extra cash for a new lense. A quicker card is not going to help you take better pictures after all, but if you’re pro, shooting on two cards is essential.

Fast and reliable
Fast, reliable, cool running, high quality memory card. Works well, clears the buffer extremely quickly and very quick to download images too. Just a little pricey but hopefully the price will start to come down.

Great product
This is the second of these cards I have purchased. Not the cheapest but certainly cope with the speed of read/write required by my Nikon Z9
