the easy to use interface. The best thing is that the user can make a customisable and very detailed training material. The best thing is that Imparta have excellent customer service and they are always available to offer help. I have a problem with one of their training material and I always get a response within seconds. The best thing I can say about Imparta is that they are always willing to help. The only downside is I wish they had more training material as the website sometimes crashes. I was able to create a very customized training material within minutes.
