All fanboyism aside, my math is accurate, according to the cheapest Chinese retailers' prices, eFun, Fasttech etc .. DNA200 mods go for around $140-149 and RX/Yihi mods go from $30-43 so a DNA200 device costs 4 TIMES more on average than an RX or a Yihi device (IPV5 on pre-order for $35 at eFun).
Reason i bring that up is personal experience, i have always wanted to buy a DNA200 device, i am a tinkerer and a tech savvy vaper and would utilize the DNA200/Escribe fully, but every time i attempt ordering a DNA200 device and see the prices difference i think to myself would it vape 4 times better? and the answer is always NO, this is why i did not buy a DNA200 device until now, maybe if i was given one or win one in a giveaway i would be so happy with it, but having to buy it at $140 when there are very decent RX/Yihi mods around for $30-43 that gets the job done makes it very hard to justify a DNA200 purchase at that price point.
EDIT: that makes losing/breaking/spilling liquid on a DNA200 device a much more costly mistake, would be like breaking a medium-range mobile/tablet, would annoy me a lot if it happens, but for an RX/Yihi device this same situation will be like breaking a cheap Chinese, move on, buy another one and call it a day!
Also most DNA200 devices' housing enclosure quality, durability, construction and finish, do not match the quality and value of the board inside which makes it worse, if a manufacturer comes out with a DNA200 device with a housing, buttons, 510 etc.. that matches a high-end phone or personal electronic device and give 2 or 3 years hassle-free warranty for it then this would be a different story, but it is not currently the case.
