It was overpriced, undertested, and they don’t know if it actually works.
They did however not have any problems shelling out $225,000 for it <_>
The best part is they think they can force the manufacturer to refund their money if it kills the network like the last filter they tried. I lol’d, realized they were serious, then lol’d harder. That’s like buying a Camry and telling the manufacturer you plan to return it if it doesn’t perform like a Mustang.
