**Update in 1 week** I've only worn 2 of the 5 so far but they don't seem to match in size. The first one fits great and doesn't slip off (for some reason the tag said it was a kid's tag even though it's the same size). The second will NOT stay on my face unless I pull my back over my head. It's only slightly weaker than the other, but it makes a big difference. First, the returns on these things have to be astronomical. If these things cost more than $1 to make and package I would be stunned. The material is very thin (a plus for the intended use, to be honest) and the packaging looks very cheap. BUT for what I bought them for, they are worth the price! They are just the right size for me, you can actually wear them as a face shield and not feel suffocated and the repeated use is amazing. I wish it was in the past but I didn't have a good reason before COVID. It's much more convenient and comfortable than a mask. The only downside I see is that my sunglasses still fog up when I wear them. Based on photos of men wearing glasses on the street, I figured maybe they wouldn't. I also received the EXACT samples I ordered.
