I am currently going through IR training so was looking for a tool to help me plan routes more effectively. My summary is that the tool is very comprehensive but lacks usability when compared to VFR products such as Skydemon. VFR to IR planning more often than not comes back with no routes and the error messages don't tell you why. The videos on help are OK but don't show you what to do when you hit problems. Editing routes on the screen I haven't managed to do yet. Response time on the server is slow in the afternoons when the US comes on line(I presume). The application works much faster under Chrome than I.E.11 Hope this feedback helps
