O.K., here's another opinion, and you know everyone has one, but with exposure to many examples from many different manufactures, the bottom line is that in the world of quality aftermarket racing connecting rods in the marketplace the China stuff, and yes there are different grades of it, is all pretty low on the totem pole from the standpoint of durability & survivability, but may prove sufficient, ......................sometimes.
Noted issues in comparison to units one would spend more money on:
Dimensional sizing not as accurate, be sure to inspect all dimensions (as one was going to do in any event), as often requiring resizing of big ends is required, pin-fitting (which is O.K.), big-end & small-end not in alignment, lengths & widths off "some", etc., all as in "came-out-of-the-box" condition.
Grudgeon pin bushings are softer causing greater wear rates or in somewhat more extreme situations just get displaced more readily from the load.
Rod body steel material generally is less rigid, bends, bows, pin-end elongates easier, big-end doesn't hold round as well. And as for the big-end, the problem with the "up-graded" bolt package is that often the increased clamping force surpasses the strength of the rods' bolt post causing issue with reasonable repeatability in sizing upon torquings.
Remember, it is true, you get what you pay for; but still, yes, often better than the O.E. as was not intended for racing stuff, so perhaps "sufficient"..............sometimes.
