Review (4/5): Better than expected
I hate having anything over my nose, including masks. With a mask directly on your nose and mouth it restricts the recycled air that I am already breathing. These inserts create just enough space between your nose and mouth from the mask to make it a little better to breath and speak. I was worried about the insert slipping but surprisingly it stays put, very little slippage. Just a little needle and thread to the inside of your mask and it stays put permanently. I want to give this product a 4.5, the only thing that would make this perfect if it came with some type of tape or something to secure in your mask. 10 is great to make sure everyone in the family has one or two.
