Bests & Worsts Reviews from Amazon

These work much better than I expected that's why I got the 3 count. I have a big face and nose, but it still fits good under all of my differnt types of mask. It keeps me from sucking in my mask when I breathe and talk. I'm able to put on chapstick again. Lips were so dry these last few months. I still sweat under my mask with the silicone, but it's still more comfortable than before. Some of my mask were rubbing me raw. Not any more. Not perfect, but close. I didn't use double sticky tape. I just insert it in my mask and go. Hand wash or wipe down and go. I would suggest buying more than 3. Check the measurements before you buy other brands. I recommend this if you are like me and have to wear a mask your entire work shift. It also helped to minimize fogging of glasses. Update: I'm knocking off 1 star. I sweat even more with it, but I still breathe better. Still a good buy. Use one every day.
