ETR,
Service is a relative term, I do much business in US, Central America, and China. All have there issues when it comes to communication, service, quality. If you award work to any business without doing your research into them chances are your going to get burned. Service in China is actually better then 90% of the US companies I've either done work for or placed work with. It typically takes a US company much longer to get you answers when needed then other countries. I contact our factory in CHina or other partner facilities in CHina and have answers within minutes to a few hours but if I contact a US supplier or customer amny take several hours to several days. So it really depends on who you are dealing with and what you definition of service is.
As for quality, I've had bad and good from all counties I've dealt with. Yes if you go place work in a CHina facility without first researching then you have a 50-50 chance, or if you work with a good broker you might up your chances to 70-30, but there are companies like us with our own facilities and own employees that provide great service and quality in a timely manner. We qualify everything before it is shipped, then again inspect to certify when it arrives. Not only for redundent quality check do to workmanship but to goods that may have been damaged in shipping but this is a service we provide that sets us apart from going direct yourself.
We would be glad to provide our services to you or any one you know that might be thinking about off shore sourcing, I believe you would be pleasantly surprised at the level of service and quality you would get.
