    I recommend to use the Security Vault. It is handy to keep the .exe file within the USB so you can open it anywhere. Considering the shape and size I had no issue plugin.

    Not a lot to say... bought a set of two to fulfill a purpose - provide my family member with video happiness, and leave one for a backup of important pics for personal and business. Works GREAT for those purposes. Write speed and read speed acceptable for the price point, and I'm not relying on these as a true backup of memories.
