I live in China. The locals with money buy foreign products for a reason. The local brands generally break much sooner (there are rarely warranties) and/or contain the cheapest (often toxic substitute) materials. Its important to note that when I say foreign I mean foreign, not made in the USA necessarily. Most often made in Taiwan. Chinese people equate Taiwan/Japan/Korea in the way many westerners think of German cars or japanese electronics. Generally made of quality materials and craftsmanship.
There are definitely some gems that I find here and think, wow I can't believe we don't have this, or I can't believe how cheap this is compared to the US". However the majority of the time the products for the chinese market are essentially disposable.
For me I try to find a quality product, preferably with a track record of reliability. So do your homework, preferably with a native speaking Chinese person, if you plan to buy domestic Chinese products. They will be the first to tell you that a lot of it is cost cutting junk.
However let me look around because there are definitely some good buys here (as there are everywhere). Could be a good thread about international products. Its actually quite simple for me to get anything from anywhere here because of Taobao which is like amazon but with individual sellers who either import or buy things while abroad and then sell them here.
