Lot's of disinformation on this thread.
So I'll repudiate a few and sing the lauds to sub ohm
vaping
1. Batteries- Lithium Manganese Batteries chemisty are fairly stable. I've shorted 3 of them in my life, in all cases they heated up fairly slowly and the top popped off. Never was burned. If you are Sub Ohm and using a Lithium Manganese and your mod is well vented. No worries.
2. Batteries- I vape at .37 Ohm and use a Panasonic 2900 The Panasonic 18650pd lasts for the whole day. When the battery is at 4.2v it 'v-drops to 3.4v and when down to 3.7 it's at 3.20V. Depending on the configuration of your mod, and your battery you don't necessarily see a huge change in vaping temperatures.
3. Taste is subjective, but the level at which I vape you can't do it on any VV device. So to reach my desired configuration, I'm in a sub ohm situation. And I can only use a mechanical.
4. Simplicity- No fiddling with LED displays, No worrying about blowing out electronics. I RBA and make a Coil that is perfect for my configuration. By the way. I use FC-2000 Porous Ceramic Wick and a Reomizer 2 along with 27 Gauge Kanthal. My wicks last more than 2 months.
5. Sub Ohm Vaping is a different vaping experience. The Coils that are used are much thicker, they heat up slower and the taste is different. It's not just about blowing huge clouds, it's a taste preference too.
At this point in time, Mechanicals go places that VV cannot tread.
