Review on UGREEN SD Card Reader USB 3.0: High-Speed CF Memory Card Adapter for UHS-I SDXC SDHC Micro SD, Read 4 Cards Simultaneously, Windows Mac OS Linux Compatible by Paul Bijeaux

I have all four types of memory cards that this reader supports and it's nice to have them all in one device. I don't have a USB-3 yet and it works great with my slower old USB-2. One downside is that it doesn't like my USB 2 ports and I have to fiddle with it to get it into the slot. This is a mechanical fit issue and I found a way around this issue. (with enough fiddling) Once connected everything worked great. Leave enough free space around the USB ports. With memory cards installed, it's a real side room hog and can interfere with devices in ports next door.
