I had ordered me a total of 4 different masks V (2x yellow, 1x white, 1x Golden). That is why I can also make a very good comparison.
The product is probably offered by various sellers and send them well sometimes different masks. Why go the opinions expressed in the reviews apart extent.
My mask I of Zeil24 (Photos are available). These sell the mask with yellow tinge. This example is but beneath contempt.
The mask is very well made, the sprayed colors also no fine spray, it does not have nostrils but a breath doing very well through the mouth, the mask does not smell and has no sharp edges. It was also everything cut cleanly.
She wears well, but sits quite tight on the head. The 2 small foam points at the back are a little larger, thus the mask is not directly on the face which is good. However, the lower foam point expresses a Bissel on the chin.
I can only recommend this mask.
Greeting Micha
