After trying other (more expensive) cf card readers which had failed after short periods due to poor design I was happy to find that this unit has great design and none of the issues of the other units I had used.... no more bent pins no more stuck cards
It has a non-genetic port on the back. Would be more versatile and it would be one less cable to carry or lose if it had a micro USB interface or a built in USB connector - like most products today.
