AMAZING! It fits perfectly, even on small women's faces.
It must be used correctly by fastening it to the back of the head. Only this way can greater protection be ensured.
A very good choice for the elderly and those who are suffering.
Flawless application, high protection combined with easy use.
Much easier to use than the 3M type.

I have purchased over 100 pieces so far.
Out of these, 1 or 2 had an issue with the elastic, the rest were very good.
It fits very well, you feel that it protects and with the clip inside each bag, you can wear it without resting it on your ears, which makes it comfortable for hours.

It does not fit well at all. You think it will be better with the sponge, but it's not like that.
The sponge leaves a big gap in the nose, on one side or the other (or both), and a lot of air passes through when you breathe. So whether it's FFP3 or not, the mask is useless. The problem is in the elastic, which is so soft that it doesn't hold its shape at all, so as soon as you put it on, it immediately stretches and doesn't tighten at all on the nose, allowing air to pass through. Also, the sponge would need more material. But the manufacturer cut corners... We tried with 5-6 masks and they all had the same flaw. With another brand of FFP2 without a sponge but with good elastic, which I shape as I want and it holds, I wear it for hours and no air passes through.
