The reg hammer has the potential to make dripping the preferred method for many by default. I have a half dozen decent rda's that I don't use anymore. I'm not even using my kayfuns much anymore. I've gotten lazy. I can get a good vape out of dual coil tanks and I don't really care about the cost. I go through 1 head a week. $4-5/mo doesn't really dent my budget and it's so easy to switch a head. If all that goes away, I'll go right back to rda's and rta's.
If innovation is allowed to stay in the market I can envision some incredible directions
vaping can go in. Like a chip controlled device that uses micro injection into a chamber that mixes nic and flavor separately so you can dial strength of both with each vape. Multiple coils that can be fired in any configuration. No wick and self cleaning. Full control of nic strength, flavor strength, volume of vapor, and temperature of the vape with built in protection from burning the juice. A relatively inexpensive coil pack that can last a month or months.
