What number of sales on a weekly, or any basis for that matter would be an indiction of "significant quantities"?
I would be pleased to see them get above a hundred a week at this point in time. They have six installation centers and eight remote vehicles that we know about. 100 units a week works out to only 6-7 units per week per installation center/vehicle. That should certainly be possible. Even at a profit of $100 per unit, that would translate into $130,000 revenue (net) per quarter.
