Best Chatroom Plugin

I was looking for a Chatroom solution for a small group of developers. I am running the latest version (5.4) of WordPress and tested many other products that simply did not work.
I had about given up until I installed Flyzoo, it was working within minutes. After a little poking around in the settings I was able to get things setup exactly like I needed and it is working great. I have it setup as one private chatroom which only allows access to WordPress registered users.
The cost is very reasonable too. The basic Wow plan is all I need for my application.
I highly recommend this product.
