hmm, I don't see the big deal. World wide supply of bearings come from china, and they have of the tightest tolerances. Back in the day Japan used to have the same image.
If your turbo fails, it will most likely be under warranty. IMO if you got a head on straight and you do proper maintenance check at proper intervals, and 1 year of boosting. If something is going to fail, it's going to fail or show signs of failure!
