CFexpress Type B and SD UHS-II Dual-Slot Memory Card Reader by ProGrade Digital | USB 3.2 Gen 2 for Professional Filmmakers, Photographers & Content Creators

For some reason my Nikon won't connect to my iMac to transfer my photos from the new Z8 memory stick I got, the CFExpress. So I had to buy a card reader. I wasn't going to go for a cheap one because I'm sick of things being cheap, but this was affordable with the right reviews for me. It only took about 15min to transfer 2400 photos into my Lightroom. And I checked the heat on the reader, and it's not too hot. It's warm, but not enough to burn you and complain on Amazon about it. It is an excellent purchase and well worth the money. I figured it would've taken an hour to import, but no. 15min is nice. Don't know what other readers do and how long it would've taken, but for how many photos I took (including a couple video files!) I'd say if you're on the fence, get this. The one con is the magnet doesn't help us Mac users as there's nothing to use the magnet on. But that's okay cuz it's only temporary and I can put it away when done.

PROS:-The reader has a magnetic base which I love. This means that the reader isn't just dangling from the end of a cable and can be loaded/unloaded with one hand while firmly mounted on a PC case.-Reads SD cards.-Has a heavy build and manages heat well. The unit itself does not overheat but the Sandisk 256GB Extreme Pro CFexpress card gets almost too hot to touch at 400MB/s. I think this is a mostly a limitation of the card's heat management not the reader's. I can't imagine how hot the card would get if writing files at the card's advertised write speed of 1200 MB/s. Again, I presume this is a limitation of the card and not the reader firmware design.-The reader mounts the XQD card (status light comes on) but so far does not recognize it in Windows 10. I am hoping that this functionality will be added to the reader with a firmware update by Prograde. There is really no reason that it shouldn't since the Nikon D850 camera can now read both cards.CONS:-I cannot get the reader to recognize the NIKON XQD 120GB card which is the same form factor as the CFexpress card. Hopefully this functionality will be added by Prograde with a firmware update.-Copying 130GB of random photographs from an M.2 drive folder to the reader on a USB C SS10 3.1 (red) port took about 5 minutes. The highest transfer speed was about 400 MB/s.-The CFexpress card gets almost too hot to touch at 400 MB/s write speed. I mostly blame this on the card since the reader stays cool.-The CFexpress card stays almost too hot to touch even when sitting idle in the reader. That is pretty typical behavior of many USB thumbdrives when plugged directly into a workstation port but I'd think that the reader firmware should be able to put the card on idle to avoid this. I count it as a CON unless proven otherwise. Leaving the card in the reader for an extended period of time will damage the card.-I can't really imagine this unit transferring files anywhere near the advertised card write speed of 1.25 GB/s. That is about 3x the speed that I reached but it may be possible for short periods or for a single large file. Also I imaging the heat production in the card would be much higher which is just not healthy for the card.

Fast and reliable - just what the photographer needed. It’s a workhorse and serves my needs for quick transfers from my media into Lightroom for editing.

It was nice and compact - definitely smaller than I expected. It’s also sturdy and fast. No complaints.

I recently purchased a Memory Card Reader, and initially, it worked great. However, after some usage, I noticed it started getting excessively hot during operation. Living in Georgia (the country), returning the product posed some challenges, but the support from the company was truly exceptional.Despite the difficulties in sending the product back, the company's customer support went above and beyond. They promptly addressed my concerns, understanding the unique circumstances, and sent me a brand-new replacement. The new Memory Card Reader is now working perfectly, and I'm quite satisfied.Overall, I would give the product a 4-star rating for its functionality, but I have to commend the company's support with a 5-star rating. Their responsiveness and willingness to resolve the issue efficiently turned what could have been a frustrating experience into a positive one. If you're considering a purchase from this company, their outstanding customer support is a significant plus.

The ProGrade Digital CFexpress Type B and SD UHS-II Dual-Slot Memory Card Reader works great for transferring files quickly. It handles large files with ease, and the dual-slot design is super convenient. However, I’ve noticed it tends to get quite warm, even when not in use. While the performance is solid, the constant heat is something to watch out for. Overall, it's a reliable card reader, but the heat issue could be improved.

I recently rebuilt my photography post-processing PC for something "more modern" in the Windows 11 space. One of the things my previous computer had was a built-in card reader, so I found myself looking for a new one. This has been absolutely awesome! It's connected to a USB 3.2 USB-C bus on my external disk enclosure unit and just "feels" rock solid in the hand. It has a magnetic base (not stuck to the disk enclosure FYI) that holds it steady on my monitor base and reads both the CFexpress Type B and UHS-II cards I use in my cameras quickly and effortlessly. It's quick enough that, when needed, I'll plug in a CFexpress card I learned (after the fact) won't work in my camera but WILL work as a 128gb SSD that just happens to be removable. It's a great way to use my investments!

Fast and reliable. Have used this for 2 years and hasn’t failed. Pro grade for the win!
