Yes, too many things are made in China...
China has the know-how/capability to build good quality components....
The primary issues when purchasing from China are:
1. China has few natural resources, that why they import tons & tons of recycable material. And China's nature is to use the cheapest material available.
2. Though China manufactures a wide variety of products, many, many buyers have no on-site auditing quality control staff. The buyer doesn't find out about the poor qualty until the shipment arrives, then too late and no leverage..

We have made over 35 sourcing trips to China, and have purchased well >$350 million of products for a wide variety of clients and products There are no short-cuts, the purchase decision is made after the submission of approval samples, but then on-site monitoring/auditting is required to validate the product's quality. Our standard procedure was to have 10 random samples pulled from the mass production lot, air shipped to the USA, we would totally take the samples apart check specs/tolerances and if OK the shipment was released and payment made.

Just my $0.02...
