I like how easy it is to use for both parties in attendance, as well has having an option that allows people who aren't using video conferencing software yet can join too! The screen sharing feature works very good also which makes things easier when training others or explaining something new/different you are working out there at your desk instead of doing so over email (which sometimes isn’t always possible).
It's not much but if anyone needs help getting started this would be my suggestion because once set up its pretty simple from then forward- no issues we have been able run meetings without any problems since implementing them about 2 months ago now!!
