The angle of the mesh part is not good, and when attached to the helmet, the mesh part faces a little upward. You can eliminate it by deepening the notch in the metal part a little more. I think that it is a good product with excellent cost performance. It is useful.
Since it is a mesh, it is good for the wind. However, it seems that eyes turn around for a long time use, the usual shade of awning can not be touched. Even if I adjust the band, I think that it is tight and not suitable for long time use as well. I think that it is bad if rubbing strongly with bare hands as processing of the aluminum part is bad.
