Installed this chat and purchased the 1-month enterprise plan to use for a forum that we live-streamed to our website. The stream had 250+ viewers and 50+ chat participants asking questions and making comments in real time. We had two admins moderating the room, and everything went off without a hitch. We tested several alternatives and liked this one best because it was simple, effective, and off-loaded the traffic to iFlyChat's servers. Server response was extremely fast, and the event log is accessible through shortcode. All in all, a very nice plugin -- and the paid service is well worth the price if you don't have the server capacity (or the desire) to run the chat through your own hardware.
