What I like about it:
No tobacco smell, can vape practically everywhere (even when it's forbidden, you can just inhale from your vape and exhale inside your shirt. Even works on airplanes
)E-liquid can be very cheap to produce when you have the ingredients.
Lots of flavours to choose. From tobacco to popular drinks, to fruits.
Cons:
It requires a big battery (mod) in order to last the whole day.
e-liquids can be expensive if bought in stores (markup is usually 10-20 times it's cost)
