Received my order on the weekend. Nice masks, really great quality, no smell (as some others have mentioned). They actually feel pretty good, and the straps are strong and secure (despite others claiming they came off easy).
The only complaint I have is the metal piece in the nose bridge isn't that strong. For someone with a defined face or a larger nose, the metal is weak and has trouble maintain the shape of the bridge of the nose, resulting in air going in/out around the nose and cheek bones. Even with this being said, it's one of the nicer masks I've purchased.
Would have been a 5/5 if the nose metal was stronger. PLEASE fix this, if you do I'll buy a ton more of these!!! :)
