Review on 📸 UGREEN 3 in 1 USB 3.0 Card Reader for SD, TF, CF Cards - Windows 10/8.1/8/7/XP, Linux, Mac OS Compatible by Isaac Ismail

I like it but I didn't think about it until there was nothing to suggest the card was used during use. On the positive side, the slot for the CF card is long enough. I use others that have such a short slot that it is very easy to bend the pins on the reader rendering them unusable. I lead teams of 8-10 endurance photographers and have uploaded 30-50 maps by the end of the day. . I'm using a 4 port USB hub, I'm planning to upgrade to a 7 or 10 port hub to connect some cards and when one of them finished copying I realized I had no idea got which reader is ready so i have to wait until all 4 are not running to start drawing.
