We have been using Active Query Builder for over a year and must say that both the product and support have been outstanding!

We chose Active Query Builder due to its flexibility and features, but have been truly pleased by its power and hidden capabilities. ...

In summary Active Query Builder provides excellent components, great support and a very flexible feature set. It has allowed us to provide features to our end users that I did not think would be possible in the first release of our new tools and in a timeframe that was much shorter than planned. I would recommend that anyone dealing with databases in the .Net world should be aware of this component and its capabilities!
