They were buyers, the bigger the order size the better the signal, as the pro's trade larger chunks. And did you know, mr mc worked on designing turbocharged tanks in the 90's... he is a genius and 100% nice to boot, still can't believe he took time to return my call and leave a good email, when my email was not working. I seriouly do not know how he does it... figures out how to make great engineering units, simple, powerful, and durable, runs this co, travels around the world on sales, talks to the usa gov, tries to keep everyone happy,... I wonder if he gets ANY sleep? But he sounded fine and happy when he left the message, so I guess it is all good and works for him. GO aftc!
