Easy-to-use interface that makes it simple for users of all levels to understand how their instruments are calibrated. The free version allows you to test out new features before purchasing with no risk. It's not as robust or feature rich as other systems like Xcalibration and Zebra in terms of its ability to perform advanced calibrations like those found in EMCs. However, I have been able to get by just fine without them using this software so far. We've used it primarily for our MQA testing process at work. Calibrating our QA lab equipment has made it much easier to make sure we're sending accurate results back to customers. Also helped us identify problems earlier than if we were manually doing manual tests.
