    This is a good storage device. I bought it for work purposes, storing documents and such for teleworking out of the office. Unfortunately about a week after I bought it, my employer has a new policy of no longer allowing detachable storage device to be connected to work computer due to fear of malware etc. Everything work-related has moved to the cloud and accessible via cloud. We are no longer allowed to use usb storage device now at work. So I have no further use for this, I wish I could return it for a lightning-to-usbC device because then I could at least transfer data back and forth between my cellphone and Ipad, but unfortunately I have removed and toss the package it came with. :-( Bestbuy, if you're reading this please consider an exchange request.
