I had to have a quick google as I know nothing about Jac Vapour. I was initially pretty excited at the prospect of getting a new DNA 75 mod for 65 - 70 quid. Then I noticed the diameter of the top plate is 23mm - the only 23mm tank I own is a clone GT4S which would look pretty stupid on it, even my MTL tanks are 24mm. I have a few 22mm RDAs but I only use them in squonk mode as dripping on tiny juice wells doesn't do it for me.
I only have a single DNA60 mod and personally I find having to connect to eScribe to adjust TC a total pain in the arse. Doing simple things like changing TC wattage involves constantly hooking up to a PC - if there is a simple way to do it on the mod I haven't found it yet, and I find the menu rather cumbersome compared to mainstream Chinese mods and not particularly intuitive. The DNA75 is also an older Evolv board and I think you may have the same issue of being dependent on eScribe to change settings unless you use the same atty on the mod However, if you are a wattage vaper it is simple to use and performs flawlessly - my DNA60 Dovpo College is more instant to ramp up and fire than any mainstream Chinese mod I own in Wattage mode, and I don't use boost. Unfortunately I don't like eScribe.
If I used lots of 22 - 23mm atties I would definitely buy this mod despite my difficulties remembering how to use the menu and being dependent on eScribe, but I don't. In this case I'd choose the Aegis Solo.
