They have a technology (FRG) that has been developed over a number of years that has been proven both internally (at Somnio) and independently.
The technology is patent pending.
PO3 has been in commercial trials/discussions with several OEMs re the use of the FRG in their respective products.
This takes time and is an exhaustive process.
Of course it's your prerogative to wait for the company to "have a product that can work", however I dare say at that time you also won't be a buyer of the stock as it will be trading at multiples of the current price.
