I can't say enough about the customer service at Drone clone xperts. Initially it did take customer support a few days to respond to my email, however once they did get back to me they were very eager to help. I have a limitless 4S I was given for Christmas. Unfortunatly it was blown into a tree and sustained significant damage. I contacted Drone clone about replacement parts and instead of quoting me the cost of the parts I needed ( which would have come close to the cost of a new drone) they proposed selling me a drone that needed repair to use for parts for a very reasonable price. The parts drone was in such good shape I was able to repair it using parts from my crashed drone instead of just using it for parts. They even sent me a video showing it's condition before sending it so I knew exactly what I was getting. Thanks Drone Clone for getting me back in the air on a budget!
