When a company wins multiple new customers for a product for which there is an enviromental need, I would say it has potential. Sales are not far off annualising at $2m, with scope for a step change with roll out eg Hong Kong Land Authority, Dalian.
So yes, Fangulator, I am serious that at $2m market cap could end up proving the bargain of the year, but, of course, I could be wrong too.
