Just wanted to post my experience with Savox. I had 2 of the MG-0255MG mini servos that stopped working. They just buzzed. Could have been from a car problem of mine, but I'm not positive. I called Savox. They answered on the first call. I was given an RMA number and told to mail them in. It cost me $2 in postage. 2 weeks later I received 2 brand new servos in the mail at no charge to me. Talk about great service. I will definitely keep supporting them.
