Review title is Did not work for me. [SEP] It dose make it easier to breath But the bracket sits just under the lower lip. The picture shows it sitting on the lower part of the chin if it would stay there I think it would be good. I tried it with 4 diffrent types of mask with the same results. For me it would ride up the chin and nose making it hard to see and talk. It is to stiff/rigid and needs to be longer than 3.5 in.
