Honestly, it's a pain in the donkey. BUT, the flavor is amazing. Way better than my KFL.
It's really fiddly, plenty of small parts.. if you want to switch flavors, you've got to take it COMPLETELY apart because of reservoir.
The draw is tight, even wide open. Not really what I like.
Also, if you don't tighten the posts correctly, the top cap of the atomizer sits "lopsided".
