I have bought my whole FPV drone setup through Banggood using multiple orders and everything was always delivered promptly. When I contacted them regarding issues with a battery, the response was fast and they solved my problem immediately.
Popkind is one amazing website full of awesome watches and other stuff. Their willingness and communication are surprisingly on a very good level. They treat me very well, when i encounter a problem. On the other hand, shipping could be faster, but it is definitely worth waiting :)
