The Swift Synco is just slightly larger than an ordinary computer mouse and requires only the USB connection for operation.
Installation is simple, just plug it into the USB port.
Data transfer is much faster via the USB port than with the serial port plus it saves draining your camera batteries during the download. I give the Swift Syncro reader a rating of 5 digicams, it operates as expected, installation is easy, and it is reasonably priced. Steve's Digicam Online, Inc.
