Purchased a $100 quad with FPV but no GPS from this company. It did not bind and I contacted the company and got nothing but stalling tactics. I have finally packed it up and after 10 emails decided just to mail it back to them and request a full refund. They had the cheek to offer me a 25% refund as the unit looked in good shape and I could keep it!!! I told them I don't need a shelf ornament and would be returning it, they have not yet offered a full refund. Won't buy here again.
