Ann: OptiScan March 2019 Presentation, page-25

Sales and revenue is only going up if the board keeps doing what it is doing right now as listed in the presentation.

Can't happen soon enough for me! But he current SP for OIL is definitely to low and measured on the market cap of Manua Kea which has an inferior product should be right now at least at 15 cents.
