Just my opinion, Never used one or seen one I real life, but a suction cup to the roof in high winds? My crash cam falls off the windscreen after a few weeks, can’t imagine this big kite staying on. As for the protection side of things, if something fell on your roof the same as last time, point of impact is going to be that same centre mounted suction cup, likely to do the same damage, who knows but to be honest I can’t see it giving much protection
