I love that we have been able see exactly what our users are doing without being there! We also like having quick access for any of us at anytime if they run into an issue or need help from another person who's not currently using their computer (like me).
There isn't much dislike since everything works great as long you know where things go once logged-in which makes sense because this system was designed by Google itself so its probably pretty good right? If anybody has questions just ask away here - support team will respond quickly within minutes sometimes even seconds!! Great customer service.
