I liked that it had an easy to understand layout, as well as having clear instructions for how users can get started with using their software easily without technical expertise (a bit like Dropbox).
The free version is limited in functionality compared to paid plans so if you are looking at purchasing this product then make sure your needs will be met by its features before making any purchase decisions! It has been used within our organisation since we first launched a few years ago now but there were some issues when transferring files from one system into another which was solved very quickly once they contacted me about them - nothing major or anything of note really although these things happen sometimes even though companies have good customer support teams!! Greatly reduces time spent searching through emails trying find documents etc., saves us money too because less paper means fewer print outs required/mailing out costs reduced.
