I order a lot from China and among my favorite websites is banggood.com.
What I can say about them is that they are trustworthy and they have a great customer service, even though sometimes you need to explain something twice. However, they always deliver what they promise and help you when in need. Also, one important thing is the fact that I never lose money because of them or a package not being delivered.
I really recomand and appreciate their support!
