I have not used it and probably never will all of my gear is Spektrum, but looking at all the information it looks like a fully developed product especially now that version #2 has been released.
It looks great for anybody coming into the hobby who already have a collection of different 2.4 Transmitters, with a range of 1000 feet it should be fine with park flyers & helicopters I would be hesitant to use it on larger fixed wing.
