I've had my Givi windscreen for almost 2 years and does not have any cracks. Many of the riders below 6' say that it provides great wind protection. On the other hand I'm 6'2" and I experience helmet buffeting at higher speeds, 70 mph and above. Over all I'm happy with the quality of the Givi and I can live with the helmet buffeting.
