Bought to assemble boot disks of various tools (Acronis True Image, Rescue Disk, Linux Distro, etc.). I really only needed 8GB USB sticks, but for an extra $3 (per set) I got 16GB. Trust the SanDisk brand and the connector is retractable. When it's outside it's solid, and when it's inside it's safe. At the bottom there is a nice stripe for the label.
