@Hooked by the sounds of reading what you have typed have you tried any of the twisp devices?
You want a small vape- Twisp
You want a light (weight) vape- Twisp
You want a vape using somercial coils- Twisp
You want a no fuss vape- Twisp
You want a pen style vape- Twisp
The only con i would say you would have with a twisp device is you will be limited to the juice you buy as their coils are made for a 50vg/50pg ratio (in a nutshell their juice is thinner compared to 95% of the e liquids vape stores sell)
So basically only twisp juice but there is also another vendor that has kiosks country wide 'Evolution Vape' where they make juice to your specifications.
We also have All Day Vapes on the forum that makes juice to your specification.
So you will have a few juice options going that route.
My wife owns a twisp ION and only exclusively smoke the juices I mix to her liking ..and I mix juices at 70vg-30pg.
a coil lasts her between 2-3 weeks.
Cannot vouch for other twisp models, but the ION has NO PROBLEM with juices at 70/30 ratio....personally I find the Twisp ION to be to weak (pap in die broek)
