The DT V4 is a wonderful cup atomizer – almost certainly the very best cup atomizer available on the market as of now (solely the M22 seemingly exceeds however that is quite a lot of 💵). You get temperature management, very environment friendly airflow and little or no wasted product due to the cup fashion. And you may pimp it with all types of bubblers when you’re into that. And it is fairly low cost for what you get. Additionally mods (battery) could be had fairly low cost.
The titanium cup is healthier than quartz IMO (and appears to be the overall consensus). And the brand new SiC cup needs to be even higher – have not tried it but because of expensive transport to the EU..
