The ease to use software is amazing! I have been trying out other video conferencing programs for years but this one has really stood up in every way possible when it comes down to actually using them as intended - which are great features that everyone should be able to enjoy without having to go through multiple steps just because they don't know how or aren't willing/able to learn new things about their computer system (which can happen).
Honestly though there isn't anything bad at all! It's very easy to set-up meetings between 2 users who may not even live close by eachother yet still being able to meet face2face easily while also getting an idea what someone looks like before you decide if its worth meeting personally or going ahead with business dealings.
