The field of view is outstanding, the M1 can here even with my Tilos Excel (which unfortunately does not fit me right ..) keep up. This creates not from my other masks.
The build quality is top, skirt, belt and mask the buckles act very valuable. The latter are also super in terms of operation: simply pull and the masking tape snaps noticeably and clean, press the button and the band dissolves again.
These suits me the mask absolutely perfect, it remains without a mask tape and without actively suck air with his nose stuck in the face, despite Beard. But happens to be different for each person.
The problems with the fogging I can not understand the way I have the mask once carefully with a hot air attachment for my gas soldering iron "burned out" and you're done. Spit clean, wash, zero-fog.
