Well if it's anything like the Gaui clone (Firefox) the plastic was brittle, the bearings were no good, and the little bit of metel was soft. Seriously, it was like the olden days of helis where you put it up and bits flew off and it fell out of the sky. Furthermore, for not that much more you can get a bettler metal CF clone, which are okay.

I have a real Trex and a clone. The clone originally was as good as the Trex but it didn't last, it wore out a lot faster and I have had to replace 50% or more with Align parts and the head is still very loose and sloppy.

Your best bet is still the real deal.

Personally, however, I prefer the Gaui 200 over the Trex.
