I agree. Sales disappoint. However the reviews on amazon tell the whole story. Works great for about 85-95% of customers. BUT - only 30+ reviews.
Great product but literally no one knows about it. They got to find a way to get the word out. And they really need to get clearance for their entire portfolio. This is still a year or so away. I hope they can find a different way to raise money as I, unlike some here, do not like the dilution method.
