I bought this the night before I needed it for a meeting where I needed to use screen sharing - I only needed Tier 1 for now. Worked great! In fact, it worked as good as any other popular virtual meeting software I've used.

It looks beautiful and I can't wait to be able to do full white label with my own domain. My client was able to share their screen with me.

Cons?
1) Wish it had a way to share a link with my client - there's no chatbox or whiteboard so I had to email the link. It's a feature they say they're working on.
2) The video was briefly pixelated/blurry from time to time. I'm not sure why. They do advertise HD video which is better than the big guys. It looked good but not perfect.

The cons are not show stoppers at all. 1 meeting so far and happy with my purchase!
