Moog vs Parts Master

[61_FL_Apache]

When I bought some ball joints I saw both names in the description.. What I got in the mail were Parts Master parts.. No where did I see the Moog name..

I know Moog using the name or term Problem Solver and I think I was confused on that part of the name..

Of course the parts came at a good cost, I just wonder about quality..

I have also read where Parts Master is made by Moog, its just their off brand.

Can someone shed some light on this for me?
