Last but not least, there's the matter of session indication: While you're hosting a session, Mikogo gives very little indication that you’re sharing your screen with the world. The system tray icon indicates a session is in progress, but Windows may hide this icon. If that happens, you could be left unaware that a session is still in progress and that you're sharing your screen with one or more participants. This could potentially lead to some awkward moments.

At the end of the day, Mikogo does work, and works well. It may not have all the perks and extras TeamViewer or GoToMyPC offer, but it’s free, and its basic functionality is robust and impressive. It is one of the best free screen-sharing tools available today.
