Anyone tried one of these HEI Distributors?

I reject about 90% of Chinese made stuff,but there is the odd piece here and there which look's right and last's. Lordco's chinese made brake part's are crap,I'll assume it's made in a plant where a bit of this and a bit of that are thrown in the metal process becuase those china made rotor's sure warp and overheat quick. The ones in my van took exactly 6 stops to warp and they also seemed to glaze over,as the stopping power just isnt the same any more.

BUYER BEWARE!
