They were a bit uncomfortable and due to the smallness of the mask, they really did not fit properly without a lot of adjustments.

The first couple weeks wearing these masks for 2 hours at a time my ears hurt quite a bit

Only complaint is that the elastic pulls on your ear a bit so it begins to hurt after a few minutes.

a bit too rigid

If you have a good sized mustache these do stand a bit proud of your face without squishing the stache .

It doesn't hurt to wear it all the time, but it's a bit expensive.

A bit pricey, but they all are right now.

The masks are far thinner than the Chinese k95's I bought in January, so they collapse on the sides a bit when inhaling.

A bit tight on the ears and design could be nicer

it conforms your face a little bit (not that well for me), then this is probably a slightly better mask than A Cheap rectangular “blue” surgical mask

Perfect - I like the added protection and snug fit of these mask.
