Would like to put in a good word for the folks at Cockpit Master. I've had their software (and interface cord) for about 6 months. Have been pleased with it. Especially the ability to download new planes as they are offered, free. Had one small problem--the interface cord wires came loose at one end and, of course, no workie! Tried to resolder but no luck. Emailed the customer service address with my story asking how much for a new cord. Immediate response--send the old one and it will be replaced free. Sent it with a check for $3.50 to cover priority mail, the least I could do I thought. New one back in about 4 days and the check was returned to me. That is geat service. Regards.
