I have installed them on all my planes. I was very afraid to fly in windy weather because clumsy landings always resulted in damage to the landing gear. Since installing it I always use it when landing and flying in very gusty winds. I've tried AutoLevel a few times but I don't think I set it up very well, but I really don't need AutoLevel as it's a "panic switch" for students who are learning and decide to fly alone without At sight. .
