Review on 📸 UGREEN USB 3.0 Type C OTG SD Card Reader - Portable Memory Card Adapter with 2 Slots for TF, SD, Micro SD, SDXC, SDHC, MMC, RS-MMC, Micro SDXC, Micro SDHC, UHS-I - Suitable for MacOS, Windows, Linux, PC, Laptop, Smartphone by Troy Kocur

Just popped it into my OTG compatible KeyOne then put in a 32GB SD card and my KeyOne can now transfer files taken from my camera and/ or move files from phone SD card. I attached them as email attachments, which is fine for multiple files, but not good for moving lots of files. As a bonus, I could even plug an old USB drive into the other end and it pulled out files and directories with no problem. I didn't trust WiFi SD cards and reviews I read indicated they were annoying and slow - I didn't want it to be just a way to move files. Now I can reliably and quickly transfer files between my camera, 2 Windows laptops and my KeyOne.
