Mine arrived last week!
It does octave up and down very well. The octaves are very organic sounding and it has way more character than the Micro POG.
However, it was never intended as a replacement for the POG. It was designed for that warbly, thick Leslie sound, not clean octaves. As a result, the octave up has a slight lag regardless of where you have the lag knob set. So those who are looking for a clean octave up for that 8 string sound will probably be disappointed.
At the moment, I'm just using the octave down and a little bit of upper octave after fuzz in my rock n roll band which sounds absolutely massive! If you twiddle around with the choir and lag controls though you can get (IMO) a fairly convincing 5 octave organ. I've also tried it on an electric piano and it sounds absolutely phenomenal.
