What kind of idiot would actually wear this - other than the finance bros this is intentionally marketed towards?
Why the mocking for people who want to protect themselves?
Normal masks don't protect the wearer much at all according to tests done in Denmark on 3000 people. However it might lower the spreading if done right. But that was harder to test with a control group offcourse.
The people making these products are grifters, and bad grifters at that being this late in the game.
199$ is way cheaper than the cost of a car and would allow me to take transit with greater piece of mind. But then again, it is cold here, and I am not sure whether and how well this product avoids fogging. So maybe not.
I suspect mask fatigue is going to have most people going maskless by summer.
