I like that they are very easy to use for our faxing needs in my role as an executive assistant at work; it's also helpful when sending documents back home through email or even directly from Outlook/Outlook Web App (OWA). The interface can be difficult sometimes but if you're willing enough there aren't many issues once your used to their system - just go slow until everything clicks into place :) Nothing really dislike about this product so far though we've only been using them since April 2018 now- which isn’t too long ago yet!! We have had no problems thusfar other than some minor glitches here &there where one person was having trouble logging onto OWA via mobile device due to connection speeds etc., however after contacting support multiple times over several weeks nothing has changed regarding login access.
