Beside my older Sony MRW-G1 CFexpress Type B/XQD Reader, I use a Lexar RW520 combined SD card and CFE Type B reader.
Apart from the very short cable that comes with the Lexar, I am completely satisfied with it.
For about a year now, I’ve been using the Lexar that Vento, Kaplah and Scott mention here
It has significantly more mass than the popular brand that others have been using for so long. And it also has 4 rubber feet so it does not slide at all. I like it a lot.
