Most people are getting their orders through fine. I've read nothing but success stories here when it comes to Chinese suppliers.
But it wouldn't be a stretch to say that it's generally an area of concern for everyone placing these orders. It's a possibility that there could be trouble. If you're willing to take a pretty small risk, it'll probably turn out fine, but if you'd rather save yourself the stress, there's plenty of great (albeit slightly more expensive) US/UK suppliers.
