Review on 🔴 High-Speed SD Card Reader, JSAUX USB 3.0 SD Card Adapter 5Gbps 2TB Capacity TF SD Micro SD SDXC SDHC MMC RS-MMC Micro SDXC Micro SDHC UHS-I for Windows Linux Chrome, 2-Slots Simultaneous Reading - Red by Travis Oetting

Pros:+ Works. most of time. Cons: - At best, half as fast as my other card readers. - The speed will be greatly reduced if both cards are used at the same time. [My other dual readers take 50% hits on each card and both are used, but this one gets 50% hits on one card and then dives on the second card.] - Some Fat32 format cards that I got with 2MB / ps, although it's over 90 MB/s on other readers.
