Got my replacement DNA75C's this morning. Evolv asked to ship only the board, no screen, but they sent back what looks like new retail boards with screens so I have 2 spare screens
. I was hesitant to upload a theme but did one and tested and worked fine so I did the other. Just the enhanced stock theme from the Evolv forum because it has a few extra features that I like. Weird that I had to shave the up, select and down buttons to work with the new boards. The Shapeways screen holder positions the screen perfectly centered in the cutout. I like the VT510 better than the MC 510 because the flat platform holds an atomizer better. The spring might be stronger on the MC 510 but I've never had an issue with the VT510 spring. I'm on the fence about the magnets. The back cover seems to move around a bit because there's no tabs to hold it in place other than the magnets. Overall, I'm very happy with the 2 new Silo DNA75C mods.
