i owned two WiaWis Frames:

The Radical and the Waws (i belive booth where the 1st gen)

both where incredibly good.
i loved the Radical more than the Waws since it was more compliant.
They are made in Malaysia in their own factory, and i truely belive them.

The first frame (Radical) was destroyed by the airline and is now on the turbo trainer, the waws frame got sold since i didnt like the aesthetics
I know couple of people riding newer models, and hadnt heart any compaints from them
