I like how easy it is to navigate, customize your course materials etc., It's very user friendly! There are not many features that aren't customizable but those they do have you can easily add in yourself if needed or ask their support team about what would be best suited for you. Their customer service has been outstanding as well when ever we've had questions/concerns with our account setup. They also provide additional services such as hosting webinars which helps us stay connected even further than just through an LMS alone. We haven't found anything specific yet where there was something lacking from them other then maybe more customization options? But again this isn't really much of a problem since everything else seems great so far :). The most helpful thing i think is having access to all my courses at once rather than going back-and forth between each one individually - makes things easier.
