We ordered a quad copter and received it almost 3 weeks later. The copter is ok but the controller for it does not work. I emailed the customer service dept to ask for a replacement controller. They sent a reply asking for a 'video' of what was wrong with the controller. I emailed the video as requested. I received a reply that said: "you can check the circuit of controller, maybe there is something wrong with circuit." How would I know if something was wrong with the circuit? Wouldn't the warranty be voided if I opened up the controller? This is Bad Customer Service! They should have sent a new controller immediately and asked I return the one that didn't work. Will not order from here again. Bad Experience, Bad Place, Bad Business Practice, Bad Customer Service, Bad, BAD, BAD!
