I have a Delkin CFExpress Type B card reader which works very well. And it is quite compact. But I had also gotten a ProGrade Digital CFExpress reader because it also had an dual slot for reading SD cards. But then I recently read that the ProGrade reader was magnetic and could damage a hard drive if it came in close proximity to it.
So I took the ProGrade reader and indeed did find that it was a fairly strong magnet when I brought a metal object next to it. Not the case with the Delkin reader.
Since I travel with my card readers and my external SSD hard drives in the same pouch, I worried about damaging the hard drive data. I don't know if SSD drives have the same susceptivity to magnets as non SSD drives. But out of caution, I think I will not be traveling with the ProGrade reader for now.
