I was doing some further reading on the Drosrite deal and came across the below on another forum...

According to a VP of the company the 4 undelivered Drosrite units take up 30,000 sq ft (with 30' ceilings!)

So I looked at what PYR says about their physical space and they list 2 facilities of 3800 m² and 2940 m² for a total of 6740 m², which works out to 72,500 sq ft.

Nearly HALF of their facility space is taken up for years by unshipped, unpaid for Drosrite systems?! Good lord.

Or have they rented / leased further storage space? Who is paying for this storage?

This isn't just a matter of unpaid receivables, this is costing them serious money! 30,000 sq ft of space isn't cheap. They're literally paying monthly for this customer to not pay their bill.
