I recently purchased a new Macbook Pro with touch bar. It offers 4 usb-c type thunderbolt ports. Unfortunately, all of my existing plugs are stardard usb, including my thumbdrives. This USB flash drive by leizhan offers the convenience of having both usb-c and usb plugs. This allows me to plug in the drive to my newer macbook pro and then transfer files to my imac using the regular usb plug side.
