Review (5/5): 5th One I tried
I kept trying different brackets. These are just right. they settle high enough on my nose to be stable, and not so high that they aim air right up my glasses provided I make sure that the mask fits snugly. They hit fare nigh down my chin to be stable while talking, soft enough that the way they hit my face is not uncomfortable, wide enough to hit my cheek bones, and raise the mask enough for both breathing and talking. Many were too small, hitting from the tip of my nose to just under my bottom lip, another was quite large and did not fit under my masks. (I kept the over large ones as they seemed like they would help with those pull up neck scarf looking ones, and indeed, gave one to the tow truck driver who came yesterday and he loved it.)
I have ordered 20 more to give away, I find that many do not know that brackets are an option, and how very uncomfortable those who must wear them all day must be.
