Bests & Worsts Reviews from Amazon

This product didn't work for me. I've found a piece of rolled up Kleenix, over my nose and under my mask, works better than anything else I've tried. UPDATE 4/10/21: Got an email from the seller offering to refund my money if I would remove my review. That tells me they don't care that they are selling a product that doesn't work. All they care about is that potential buyers not know the product doesn't work. I don't support liars or cheats. I would be very hesitant to purchase anything from this seller in the future.
