As for atomizer lifespan I would say one week seems to fit my experience. Some last 2 weeks some 3 days and some 1. I drip, and frankly don't like dripping, vapor production is very hit and miss with lots of problems with ejuice. Either it's the juice, the atomizer or the cartomizer Cartomizer consistency I've found to be very low then they just end up tasting bad after a short time. The atomizers I find more reliable, but they're like 5 times more expensive per unit. I must be the only one having bad luck I've been vaping for about a 8 months now.
I've just been doing 3.7 volts. 1.5, 1.8, and 2.0 ohm cartomizer/atomizers. I've had some times when my vaping was so great I wished it lasted forever. Had some tasty vapor geoff's blend that was perfect with a 1.8 ohm cartomizer. Warm clouds. Got another batch and it was really mediocre. Using same brand/ohm cartomizer, but with diferent VG/PG ratio. Then if I get too high a ratio of VG the juice starts to taste burned.
As for lasting 510's I've found the titan's from that awful totallywicked.com to be the longest lasting, but the service and everything else about totallywicked I can't stand including their juices.
Vaping is unreliable at this point for me. I too want a reliable vape. I bought one of those mega ego xl atomizers. It's huge and for me it sucks. I guess you can't drip into one? It didn't come with a cartridge. I hate cartridges I really don't want to be surprised with a huff of burning plastic. Yuck. Anyway that's why I'm here... to learn.
When it's good it's great, when it's not, it's frustrating!
