Here my brief review:

Order: and delivery no problems and very fast (2 days to germany)
Installation: very easy (every step described in the manual)
Setup: no problems (thx to the wizard) The only thing was that with Jeti you have "incredible" small servo travel (68% in FW 1.3.2)
Tuning: some problems, because my heli (Oxy 3) had some trouble before (first vibrations from tail and then a wobble on the main rotor) but this leeds to the next point
Suport: really great Support here in this forum

Compared to my other FBL systems the Spirit has the following benefits:

reproducable adjustments (numbers vs. poti settings)
fine tuning by transmitter (gains, etc.)
rescue function w/o upgrading
vibration analysis
flight log
the flight performance is really good

Many thanks to the developers
