This mod 18650 based VV for 35-40€ will if it works well be a game changer. At this time even simple 3.7 volt 18650 mods are often more expensive. On the VV mods, not even the madvapes linear regulator 14500 based is any cheaper. So this could mix up the whole modder market.
I dont think buzz, provari darwin or alike will be afected. Their products are bought by people who are looking for a high end mod, or for estetical reasons buy them.
The mid market will be afected, because here many of the mods moving, have simular or worse specs, at higher prices.
The entrance market will be very afected, I dont see the modders offering VV mod boxes hold up at these prices.
Then I also must say, mod boxes VV still will be bought by people like me, who wants a mod delivering huge power, no matter how it looks, firing at anything you might throw at it. IMHO.
