Sony's Micro Vault 'Click' USB drives have no caps to lose and do not expose the USB connectors when not in use. Their unique design employs a clicking action similar to that of a retractable pen. When clicked, the USB connector is extended for easy use with computers, televisions or any electronic device that utilises USB port for the transfer of information. In addition, the prism 'LED' indicator illuminates when the Micro Vault 'Click' is connected to a computer and during data transfer.
