Looking at their recent presentation compared to their march...

Looking at their recent presentation compared to their march quarterly, they have only contracted 2 units in the last three months. The number of commercial proposals has actually dropped from 13 customers to 10. Engaged leads have increased so let's hope they can turn those into proposals and then contracts. I am guessing they would need to have sold around 30 units to break even, so with a market cap of around $39m its not cheap and they need to be adding a lot more than 2 units every three months. I do like the technology though.
