I have used this site a couple of times and have found them very good. The second time was a quadcopter, it had motor issues so they sent me a new motor. When it happened again I got onto customer service and they refunded all my money back for the quad. Their customer service I have to say was excellent and the time to get the product was very good especially seeing it was over the Christmas period. I will be buying many more things of them after the good service.
