Welcome and glad you joined. Years ago tried the Vape4life products and I think I know where you are at and what you want.We have been fairly happy with the 900 mAh Vapor Zeus dual mode battery but I hate the way we are stuck with the 808D threading which has basically left us with only the one option for the tank (well, with 2 sizes, 3.5 & 6 ml) which uses the undependable cartomizers and the tanks are not consistant (some leak, some don't work well and tastes burnt. The size we use is slightly over 5" and becomes nearly 8" long with a tank and tip. I do like the plastic drip tips. They feel best on my mouth. Although I have broken several tips when my ecig falls off my lap when I get up and hits the metal leg of computer stand. (I work all day on my computer at home) I should have learned better. :/ Neither of us liked the 'Smileomizer' that comes with the Zeus.
I thought someone said the Nautilus wasn't for me....and was a messy bottom fill.
1. Simplicity and happy to vape same (2 or 3 flavors maybe) flavor for most of day. Not having to recharge frequently.
2 Cost, V4L is expensive so you are more willing to spend $ up front in order to save in having to pay on going cost.
3. Above all, you need dependability.
Got to go now but will be back (someone else can help) to see if I am correct. Is this what you are after?
