Not to say that all US or Canadian manufacturers make parts that are perfect, but they do tend to have a much better track record when it comes to dealing with defects. I find that the price penalty of buying from them also gives me peace of mind when buying their products. Unfortunately, there are lots of items that are not made in the States or Canada and lots of weeding must be done to find the best of the junk made in Asia. Some US sellers of Asian parts actually, at the least, go through an initial approval process when a new mold is made and some just take the factories word that it is good. The latter procedure was in place at a US company that I interviewed at where they made fuel filters for a major name filter company. To check the filters they capped one end and shoved a hose on the other end and the operator dunked it in a 5 gallon fish tank and blew into it. No bubbles and that batch of one hundred was declared good! Turned the job down and have never used a filter of any kind from that company.
Perfection is hard to achieve but pretty good isn't and many companies can't even achieve that.
