LifeLeaf, noninvasive CGM wearable currently in testing

I have never seen or heard about this CGM! Anyone here had seen it before?

Here the link to the LifeLeaf

This has been in the works for a while. Not sure if it was under this company name though.
I was VERY intrigued by it when I first heard about it!
Kinda of forgot about it though.
It would be very interesting to see what kind of accuracy it will have.
And the cost of course.
