The most useful thing about this product is that it simplifies storing data at any time of day or night. It lets me work while I sleep! No more forgetting to save my documents before going home for the evening. This allows me to stay organized all day long without getting distracted by other tasks. Sometimes using dropbox requires some extra steps in order to sync with our CPIs properly. Sometimes we get errors stating "Dropbox cannot be reached". But once fixed, everything works perfectly again. There are no issues with syncing with our CPIs. Our clients use dropbox as well so they can send us their documents securely through email.
