I own quite a few mods, so the DNA200's I do own get used in some form of rotation-but here goes.
Hotcig V1-(My first DNA200, had its board replaced within a month of purchase, failed the day I got it)-7965 (Wow, I should use these mods more, 11 months old, I do own 26 regulated mods though lol).
Hotcig V2( Failed within a month, board replaced within about 2 weeks-was sent for free due to the issues I had with the V1 only to develop the same issue lol)-2325 puffs.
This states since reset, so it may of been more, or I have hardly used the device at all!
Efusion-(Worked since purchase, only issues have been with hotcigs)- EEPROM read kept failing, I am using VirtualBox as I am on a Mac, I can't install bootcamp due to a broken superdrive, tried to force the mac into thinking it was a model without a disc drive to install an ISO but no luck. So no data right now, sorry about that.
Finally, the Wismec DNA200, which is my favourite, - 7861.
After doing this, I realise they have not had much use at all, much less than I thought they have had. Assuming the Efusion falls into the same range, it will be somewhere between 2000-8000 puffs.
I had a near heart attack moment, when I just connected the Wismec, in device monitor, it was showing the voltage as just 1V for one cell, and the others all under 1V! I then realised it had no batteries in lol.
