It is very good to use, it has so many options for different needs that you can choose from easily.And they have also made some customizations as per your need like we had customized our chat box design & colors according to user's preference which was really great! I don't think there are any cons in this tool but if anyone would be having problem with using then i suggest them try their support team because its free service provided by Ajaxworkspace<br / If someone wants more customization than standard features just go ahead! And yes definitely worth trying out even without paying one should get benefits after few months or may years when u will work hard enoughtly ;) We were solving problems related customer interaction over webchat room where customers could interact through video chatting.
