Some guy in Santa Cruz, CA has/had one, and did not like the quality, from what I remember. I think he said it wasn't stiff enough when put into trike mode. You may want to see if they offer a money back guarantee.
If folding trikes are your thing, I think, on paper, Greenspeed offers the best bang for the buck. HP Velotechnik and most other competitors are way too cost prohibitive or don't import to the US. You can also get a fairing kit for the Greenspeed and turn it into a ghetto velomobile for another grand.
