Very recommended. I like it.
Zodiac.NET is very rich and easy to use component for .NET development. It has a very rich and easy UI for users, it is also affordable and available in different licenses. The support is helpful, responsive and fast in replying to the inquires.
You may need some development effort to include it on your web site. You will need to get a .NET developer to integrate it to your web site. The online help is good but you may need to contact their support sometimes.
