Anyone know anything about these no-brand "LWD M 20/0.30" Objectives?

I've seen a similar objective that had a WD of 12mm, which is nice for 20x, although the NA is a bit low. "5 sold" already, so someone's trying them.
Thanks,
Tim

These are no name Metallurgical incident light objectives from "China Incorporated". They are of reasonably good quality when used visually.
I have a set of them on a reflected light microscope which was originally intended to examine fiber optic ends. I have not attempted to shoot any pictures through that scope but when I look at things through it I am reasonably satisfied with what I see. The build quality also seems to be adequate.
I am merely reporting my own experience not vouching nor recommending them.
