I was part of the initial Kickstarter, and I was really looking for PPE that went beyond the simple masks we had at the time. I bought 2, for my wife and I, but by the time it shipped, simpler KN95 masks were available. The UVMasks were too heavy, hard to breathe through, poor sealing, too loud, and sat on the face in a way that made even simple facial expressions disruptive to what face seal was available. The built-in fan, touted as a way to ease breathing, does not appreciably help at all.
These units were shipped, and were received. I do not agree that the company "is a scam" but they clearly could not provide a design that provided the feature set they claimed, at a price they could realize an appropriate return on. It's a good idea, but this implementation is just not good enough to use, let alone purchase.
