I like that it allows for quick prototyping of models, as well as being able to easily modify them later when needed (the model can be downloaded from an online repository).
It's also easy enough so someone who has never used Simulink before could use this product without too much trouble or learning curve issues - which was important because we were looking at using something more general than what our existing team knew how best with their background/experience in simulating different types electrical systems / components. We are currently working together within one project but have moved onto other projects now due do requirements changing during development phase etc; however still continue work towards completing initial goal set out initially by another colleague involved previously!
