I have been surprised that only the Boxer Squonker, the Lost Vape Paranormal & the Think Vape Finder have released a DNA 250C mod. I was fully expecting Hcigar and a few others to release a DNA 250C as well. Evolve does not want to compete with their wholesale customers or do anything that would hurt their wholesale customers sales. I believe releasing the DNA 75C ‘Replay’ upgrade might negatively impact the sales of their wholesale customers. I believe Evolv is waiting for the buying surge of DNA 250C mods to level off before releasing 75C update. If, indeed, there are more 250C coming out in the near future it will be awhile yet for the 75C.
Just my 0.02 cents adjusted to $2.00 for inflation.
