Losing USB end caps can be quite annoying not to mention the inconvenience of taking the cap on and off every time the drive is used. For extra convenience and protection the JetFlash 500 flash drive is designed with an innovative extension and retraction mechanism that enables users to bring out or hide the connector with a single flick of the thumb. Its capless design not only keeps dust and debris out of the drive but also ensures there is no cap to misplace or lose.
