It served its purpose very well. However, out of the 50 masks I purchased, some are defective and tear under the chin, but they still cover the nose and mouth. Otherwise, it is quite good quality with large elastic bands.

The only observation I have to make about this specific mask is that for a female face, the elastic bands need a little stretching because they "pull" the ears. On a male face, which is larger, the elastic bands are quite bothersome. They need to be bigger.

I placed an order for KN95 masks and they ended up sending me FFP2!!! They have no comparison in quality to the ones I have purchased from a pharmacy!!!

I expected something different and something else arrived in the end.
I was expecting KN95 from the photo
And FFP2 arrived instead
It is very tight on the ears, so much that as soon as you wear it, it hurts and bothers you immediately!
And I had ordered 40 pieces too!

It came with a large white Berticar logo, which is quite unattractive and does not match the photos of other users, maybe every store sends whatever mask they want, which is problematic...
Also, they were quite big compared to other similar masks.
However, quality-wise, they are good.

The KN95 certification is Chinese while the FFP2 is European. Essentially, the performance is the same and filters 95% of airborne particles.

All good with the mask.
Much better than others of its "kind".
Great for a female face and that's why I remove one star. This needs to be fixed with the size per product code.
Fits perfectly on my husband!

Although advertised as KN95, it is NOT in every case, however, it carries FFP2 and CE certification, which personally made me not return them. Also, the packaging has a note saying NON-MEDICAL (quite concerning). Based on their thickness and the certifications they carry, I would buy them again, but I would prefer to know beforehand what to expect.
