"I read the reviews, and was still surprised how good"
Easy installation and setup; performance
Nothing so far.
1. It works. I've only used it for demonstration (that is, I haven't really needed it), but I did it with two different computers with two different ISPs, and the remote users were two different senior citizens. I installed it on the computers and showed them where the teamviewer icon is and then I later called them and had them start it up and tell me the numbers that are displayed, and I was connected and could do stuff on their computers remotely. Just like it's supposed to do. This should make things a lot easier when one of them calls with a problem suited for this sort of thing.
