The mask looks great, really creepy. They report not strict, only normal for rubber but I got used to it quickly. You can also wear well, it caught nothing. I have but the eyes have to cut something, because otherwise my eyelashes came against the mask and it was very unpleasant to blink. The bigger problem, however, is the position of the eyes and mouth. When I place the mask that I can see well that bothers me about the eyes is nothing my mouth about at the height of the upper teeth. The hot that I always blow my breath against the mask (through the nose is almost nothing that the holes there are too small and too high arranged for me). This leaves my (moist, warm) breath in the mask and they fogged in approximately 5 to 10 minutes so much so that my face dripping and the mask itself is also soaked. At the party I could wear them for a short period at a time, then I had it and dry myself with napkins. But still to schmiken better than consuming. : D
