Love this product! Bought it to primarily backup my cameras SD card and USB device, it works as advertised just by inserting the card. Backups happen quickly and reliably with no fuss. Easy to view the contents with the app on any device, and with the inbuilt plex server makes sharing media simple as. the battery doesn't last the advertised 10 hours, maybe got 8 from it. The only compliant I have (and its probably Apple's fault) is the iPhone auto backup stalls and doesn't copy all files, but I also have this problem with the phone copying to my PC as well. highly recommended.
