At the absolute most, it is vaporware at this point.
As far as I know, they have yet to show any real product (or even prototypes) beyond their renders and promotional videos.
Does that mean its a scam? Not necessarily.
They could have good intentions and are just hoping to raise funding before getting it produced... buuuuuut it is extremely fishy in that sense that they don't have anything more than it being a fantasy at this point.
Upon further review as I'm writing this, I am growing less confident it isn't a scam.
While it looks like they've put a bunch of work into their website, the majority of content is AI-generated so a red flag on that end of things.
Second red flag, there is no legally-mandated, mention of location, and there is no name/person behind it other than "the inventor"
And even just logically... how is it going to hold itself in place with just the thin strap underneath? Its going to be so top heavy and falling down.
(Plus battery life, any technical glitches, those probes causing irritation, etc)
