You can destroy any engine in a matter of minutes if you wanted to so what's your point? I could see synchro damage over 750 miles if the driver was new to transmissions but having gears go out that early usually points to a manufacturing defect. Anything is possible but driving a manual transmission isn't really that hard and unless the user is extremely incompetent it's a stretch to point to user error.
