I have not used the ProGrade Digital Compact Flash and SD UHS-II dual slot card reader for more than doing some tests, but so far it has been impressive. The compact flash well is deep enough that there is little (or no) worry of bending the pins in the reader. This is something less worthy readers rarely do, and I have many dead readers due to bent pins from shallow CF wells.
The rubberized magnetic base works beautifully. I have the reader stuck to the top of a full tower case desktop computer, and can easily insert & remove cards without dislodging the reader. I have not tried the included adhesive-backed ferrous mounting plate with my aluminum case laptop, but it works exactly as desired with the desktop case.
The only complaint I have is pretty minor - the online description of the unit says that it has has USB 3.2 Gen 2 interface, but the packaging says it’s a USB 3.1 Gen 2 device. I thought I had been sent the wrong device until I did a little research. believe this is simply a matter of the 10 Gbps USB channel being renamed by the USB Implementers Forum from 3.1 Gen 2 to 3.2 Gen 2, and it was probably too expensive to repackage existing inventory to reflect a different name for the same thing, especially when the packaging is so obviously first-class.
Overall I’m very pleased with the ProGrade reader so far.
