Quint Machine : The best octave pedal I've tried

I have tried the MXR octave deluxe which for me didn't track perfectly with either my soprano bass or my full size bass (mainly on the higher stings). I've tried the Micro POG which tracked faultlessly but to me sounded more like an electric organ and after a while it got on my nerves, I had almost given up but thought I would give the new T-Rex Quint a last chance and WOW it is utterly brilliant. On both my full size 4 string bass and my soprano bass it tracks faultlessly and the Fith option adds a beautiful almost chord like tone, and most importantly of all the octave down sounds like a bass guitar octave down and not a pseudo organ sound. A full five stars for both the sound, the functionality and the build quality, I might even try the octave up at some point, but as a bass player I'm not sure exactly what for !
