TestManager 4.0 Benefits include:
Central repository for all test cases (manual or automated) allowing for consistency and transferring knowledge to other/new test personnel as well as sharing information with development personnel. Manages test results so that test metrics are only click away. Date, timestamp and username are associated with every test result. Manages consitent testing from release to release. Each test case has estimated time which is used in estimating test efforts. Tracks automated versus manual test cases. Easy-to-use web interface. Easy to integrate with automated testing tools to report results using SQL interface. Easy-to-understand licensing. You pay for the program and a single server license and not per seat.
Cost, Cost, Cost...to get similar features from the big vendors you'll pay about 10 times more. Finally, TestManager 4.0 is built on ASP.NET technology!
