I am not familiar with this product but it sounds like it might be useful.

 

Has anyone out there that is using it can advise on whether they think it is useful or not say as compared to other tools like PlanG (freeware) and FS Commander (Payware)?

Been using it for some months now. Love it.

 

Have it on my ipad which i carry everywhere. When time permits I can create a flightplan, save it and upload to dropbox.

 

When I get home and go to the Sim, Dropbox has downloaded the Plan. Just need to copy it to the FSX folder in My Docs to use.

 

You do need to purchase Maps & Data to use in QP if you like to fly outside of the Sanfrancisco envelope.
