Banggood is my preferred provider for small remote controlled airplanes, helicopters and spare parts and batteries. So far every time I was not fully satisfied for the received items, their customer service has been absolutely helpful in finding the best solution. One time a damaged items and a couple of times quality issues have been solved with price reduction, item replacement or even full refund. Off course I always spend a few cents more to have insured international delivery. I am satisfied and I can recommend their services.
