"Works for remote support"
Lets me see and work with a remote computer(mouse, keyboard). You need someone at the other end to get the codes to start it up -- not a con, just how it works. Its free, you can transfer files (slowly), its portable (so no installation needed).
File transfer is slow. When ending the session from the controlling side, the root team player on the other side does not end. I guess that cold be good if you need to get back in.
Decent program, works pretty well. Be advised the desktop background will be blanked while working.
