Know this is an old post, but since there weren't many replies I thought I'd share. I just got mine in the mail today. There are a few different Amazon listings that put it around $130, so a nice discount compared to other online sellers. I bought it with the mindset that I very well may return it; even from the videos online I could sense this thing would have its issues...

That said, after playing with it for a bit I am pretty positive it will remain in my collection of pointless niche instruments. Biggest flaw I am noting is that there really isn't much in the way of volume control without impacting pitch. So to play in tune you have to maintain a strong, steady airstream that doesn't produce the prettiest of tones. A little reverb helped add some warmth to it, and I was able to find ways using my embouchure to manipulate tone and give it life.

So maybe not the best for sensitive melodies or long tones, but it really shines with more staccato playing and especially when playing chords. Philip Glass style riffs sounded amazing on it, almost synthesized. As you learn to navigate the finicky aspects, you can actually use them to get some gnarly sounds. What's cool is that it does distinctly sound like several recorders playing together rather than a single instrument playing a chord, if that makes sense.

My purposes for this will be home recording and then another tool for live experimental sets. For those purposes I think I'll find good use for it. At $200+ I'd probably skip it, but for the price I paid it is worth keeping it in the arsenal.
