The most outstanding feature about using orasilab as our virtual classroom platform was how easy it made setting up my class! I did not have to worry about anything technical because everything worked perfectly right away - no problems at all with connectivity issues, etc.
It's very user friendly and intuitively designed; you don't need much help from tech support when installing/setting things up. There were some minor glitches here & there but they got fixed quickly without me having too many complaints. This software has helped us save so much money in terms of actual physical classrooms needed (in comparison to other similar platforms).
