Dammit, they sold out yet again. Sheesh. I guess I need to camp out on their page.
Dimension Engineering and Evolv are teamed up. I was told that the DNA20D's are manufactured in the US in Akron Ohio which is where Dimension Engineering is located.
I am assuming that X amount of dna's are produced a day and they are put on sale that day. I found that they usually are available 7pm-8pm EST.
