Thanks, Techxen! Your answer is completely logical...but I still find massive volume hard to square with the flattish nature of the SP today. But at least we're out of the $3's and $4's and hopefully on our way into the teens and $20's. Still no downside to this product, and if we do hit 80 million filters in the next 12 months, I think a billion dollar valuation is totally justified...which puts us about $30/share.
