what do you know about aria pedals?

Been looking ať some on the hot rox uk site. Theyre quite well priced and they look good. But does anyone know about their sound and build quality? Are the true bypass etc?

They look like they're OEM'd by Biyang, the same company that makes the GFS pedals. They look good, and there's a lot of love for many of the GFS pedals, but from what I've seen the Aria pedals are a bit overpriced by US standards. YMMV, however.
