Watch the video again. Go to 00:38, and assume that the dummy was hit by a lorry with flat face. The lorry would make a direct impact on the back of the head, before the helmet inflates. Go to 03:55, and assume that the cyclist had hit a wall. This time too, the cyclist's head would hit the wall. I wouldn't buy this helmet.
