As a surveyor, I use this device almost every day to transfer files. I didn't like constantly looking for a USB drive for my data collector. This is small enough that I can store it in the collector, use it, and then put it back without interfering with my daily work. If in doubt, just buy it. It would be nice if it had a better/bigger protrusion on the outer end for easier device removal.
