The user interface is very simple to understand. Not many features are available which makes learning difficult for first time users. But if used properly its definitely worth giving the live clickers a try. I have solved many problems with live clicker by just placing and playing my ads. It was very effective to increase our traffic and conversion rate. Just few more days and all our target will go to live. It's great for team communication! This is one app I use every day as we're constantly communicating in our office about projects or issues which makes collaboration easier than ever before. Not much but honestly this could be solved by improving user interface more with less clicks needed (which would also improve performance). But overall its still good so far especially since your able to have multiple people working together while having video calls without any lag or anything like that.
