It does happen but I try to not rely on a China made product especially for critical parts.
Some parts are ok but I would hate to build something around a cheaper part then it fails now everything needs to be changed to accomdate something else just lots of extra work taking a chance when there are race proven parts made right in our own back yards!
I'm not judging ya....just answered the question. The rest is from my own experience attempting to purchase all American. Couldn't do it...at least not on my pay.
