Go with APV’s if you are a casual smoker or if you are vaping instead of smoking cigs.
Go with a mechanical mod if you want big clouds and are into tinkering with them. Mech mods require more maintenance in my opinion.
I really liked my VaporFi VOX II mod but there are tons to pick from.
I suggest you visit a review site and look at what they have to offer. You got so many designs, colors, temp controlled, watt controlled, hybrids etc etc.
Just make sure you do your research before you buy. APV’s can get expensive and you don’t want to buy something that you don’t like from day 1.
