I have been ordering stuff from Banggood for a couple of years. In that time, my only complaint is with customs holding things up. Simply put, that's life.
I have received nothing bad nor unworkable from Banggood. My latest purchase was the SJ4000 camera with wifi. Except for special photo needs, I can put my Canon 60D away.
The two quadcopters I bought about a year ago perform flawlessly and are loads of fun, as each has a camera on it, my wildlife photography hobby expanded enormously.
Only once has a part been unsatisfactory and the ease and speed with which Banggood responded gets high marks in my book. If it is excellent prices, extremely wide choice of merchandise and superb service then Banggood should be your choice!
Would and do I recommend Banggood? Yes, without reservation!
