The best thing about this software is that it can be used both online and offline. It has got very good user interface which makes it simple to use as well as understand. It does not have much to dislike here. I would say if you want something reliable then go ahead with it but do try out some other products too before finalizing one. We were looking for an all rounder product to integrate our application in. Hence we went through many such softwares like QlikView, Power BI etc. None could give us what we wanted so finally we decided upon QlikView.
