Since majority of products come from China i'd say they're pretty decent. I think most countries that specialize in manufacturing are getting a leg up on the US because it's harder to acquire that sort of knowledge without doing it where as replicating someones service typically isn't hard.
Most of the product in the world is made in China. The quality of the product is mainly depend on the price You can still get good quality product if you pay good but it is impossible to get good product if you are paying penny
Ipad, Iphone etc are made in China. I don't think anyone can say that they are bad. But the quality does vary a lot. There are a lot of fly by night manufacturers that do not care about the lives of their users and just want to make money and disappear.
I can say that it can be good or it can be bad. But so far, all those items that I have that are made in China are still working fine.
