Technical A-Team carbs and other components

I keep getting ads in my FB feed for A-team carburetors, alternators, and o ther components. I'm all for saving money, but I am skeptical of quality because the prices ae so much lower that Holley, Edelbrock, etc. Anybody have any experience with them? Some Googling led me to the info that the trademark/brand name is owned by Peak Peformance Wholesale Distributors LLC. Don't know if that tells anybody anything. No indication where their components are made.
