I like that it's easy to use as well as its flexibility in terms of customization options which makes my life easier when modeling process flows or any kind of simulations. It can be slow sometimes but i think this could have been improved by adding more RAM memory with faster processor speeds so we don't need to wait long time before getting results from our models/simulations especially if you're doing complex scenarios involving lots of variables. Also there are no tutorials available online about extend sim unless they released some videos regarding how to configure it properly. So basically what i'm trying to say here is try out different configurations until get one suitable enough since your experience will vary according to each person using them. For me personally, solving problems related to process flow analysis has become much simpler now because of the help provided by extend Sim.
