this review title is: good in theory not so great in practice and the content is: i was so hoping these mask brackets would solve some of my problems with masks fitting well enough to protect but also allow some comfort and easier breathing sadly did not happen if i even opened my mouth a little it would cause the mask to pull off my nose not good it also caused gaps at the sides top and bottom of the mask which allows my breath to escape from the mask perhaps if they were larger and flatter it might work but right now not so much.there are other information for this review, one is this reviewer did purchase it and the other is 0 people think this review is helpful.
