		I think that's a failure and a defective visor and it's not fit for purpose. How is it strong enough to protect you during a crash if closing it cracks it? Did you close it with a hammer? There's no way should you be able to crack it by closing it. I'd contact the place you bought it from and at the least they should replace the visor
