I bought this vape pen due to it's smaller size, and not wanted to take a huge lung haul off the vape. It's a great vape pen for mouth vaping, not lung pulling. So if your into making clouds. This is not the pen to be doing it with.
The only problem I have is that if I need replacement tanks, I'll have to rebuy the entire battery and charger just to get more tanks from the look of it.
