You know, it’s subjective 
it worked perfectly for me for when I leave home so I don’t have a mod+tank in my pocket where the atomizer is vulnerable and it sticks out long and is uncomfortable… also, I’m a public hazard with all these glass things like the tank
So its biggest advantage is the compact, pocket-friendly shape. If you find the best coil and cotton for you, you’ll get excellent flavors. .
I think I can confidently state that I am only willing to spend money on Aio and Squonk+RDA from now on.
