I like that it allows me to create courses which can be used by students worldwide! It's also very customizable so you don't have to stick with what they offer out of box! Sometimes there are glitches when creating new pages or adding content but their support team really helps get things resolved asap! If you're thinking about using this product make sure you give them enough notice before hand because sometimes some features take longer than expected (which isn't always bad).
Creating online classes for my clients has made our process much easier since we no longer need to go through the hassle of printing off powerpoints etc.
