Well I do know what it does.... It increases the angle of attack at a given airspeed which in turn effectively raises the nose and gives the aircraft a better feel in the decent. It broadens the speed envelope for touchdown with no bounce. Great for shorter runways like I fly out of. It also gives the ailerons more feel into lower airspeeds.

Yes I have tried it, use it and recommend it, you will be pleased with the results.
