If you are using Mac as the primary machine, I would be cautious. Otherwise, it is a great tool.
When I use the Mac and happen to run into audio connection issues, there is really no way to recover because there is not a connection wizard for Mac. From my experience, the audio issues are unpredictable and unfortunately I have been in a few situations when the only thing I can do is cancel my meeting. Using a PC, in similar situation you can run the connection wizard which resolves the problem.
