The best feature of this product was its ability to do multiple tuning with one model, so I didn't have time consuming process as before when doing P&ID or DCS/DCM calibration! It also has many advanced features such like PID parameters adjustment etc which makes me feel more confident about my job than other products in market now!! Some functions are not easy using by new users but after some learning it's really helpful once you understand those commands that they will be able use efficiently all needed tools easily.
If your budget allows then try out first because price might seem high at start compared what we can get from others free versions nowadays. !
