Very good. It secures quite well (although sometimes it causes fogging on glasses). I use the clip to hold it, my husband who has a bigger face does not. It fits well and does not bother anywhere.

On Amazon, it has amazing reviews. The company is well-known for medical supplies, so quality is guaranteed. Personally, what bothered me is the wire on the nose. It is very soft, too malleable; I don't know. It doesn't fit so well, though. Maybe it was a faulty batch. I will reorder to see. Note: For those who prefer to have the mask on their ears, I don't think it is suitable. It has a little thing to hold the straps behind. That way, it "secures" - "covers" well. Otherwise, the straps easily slip off. Edit. The fact that it has three instead of five layers is not essential in my opinion, as it relates to the material used by the company. The mask is certified FFP2, so that's it. The fact that it provides less than 95% protection has to do with leaks around the mask. It doesn't fit all faces. For example, when I breathe, the mask collapses, so air passes through it. If this doesn't happen, don't use it.
