I'm just wondering if anyone has tried Chinese carbon rims from 3S bike?

I'm a tightarse so trying to salvage my spokes for the new wheel build. Light bicycle don't appear to have a wide rim (35-45mm internal) with a 595mm ERD, or close.

These 42mm rims suit the needs of my wide tyres and the recycled spoke requirement, but I am having no luck finding independent product reviews.
