Great product, best I have tested to date, shields the user from many of the complexities surrounding SQL creation i.e. AND/OR automation and criteria repetition. The control can be up and running in no time, great flexibility in the way that features can be turned off based on application and user requirements i.e. table join creation, calculated field creation, etc... Built-in Excel reporting functionality, that also supports Excel pivot table creation, works well. Help, examples and demo are very comprehensive and easy to use. If your application needs SQL building functionality you should definetely try this one out.
