The hood can easily move there about it, even on the small front shield. Back then you can fix it with a tape tension the hood. Here, the wheel remains with the flashing light and the size adjustment freely among them.
When driving you have still a ventilation of the head by a draft between the hood and the head, did not noticeably more sweat on the head than without hood. The reflectors also not hurt. The optics I find not bad.
After driving the cap can easily remove and re-folded small. I kept the small plastic bag of the delivery and the hood can be there again stowed away.
Can not detect any defects or negative points of the product.
