Was tough finding these memory cards in stock, so I would guess they're pretty popular? They do cost a tad more than other brand CFexpress cards, but I have heard nothing but good things about the longevity and durability from these Sony cards. It's now near the holidays, so I've seen them going on sale, off and on, so look for some deals. They do seem better built and are just slightly tight when inserting and ejecting from my camera but I don't see this as a negative but more as a positive that they can handle mishaps better than other cards.

Outstanding. I heard rumors about certain cards overheating in the Nikon Z series cameras. I read some reviews, made the most informed choice I could at the time and couldn't be happier with this card. Zero issues. I've had the camera and card about 4 months and couldn't be happier with it's speed and performance.

So fast and holds a lot!! I love it. and it’s nice quality!

I just received my Nikon Z9 and needed a good memory card. This Sony card speed and size was just what I need. I shot some action pictures at my grandson BMX Races and its been great. Its speed complimented my multi frame shots well.

Has held up perfectly after nearly a year of use. I shoot RAW photos and 4K HQ video on it and never had a problem.
