Yep, took me several tries to get vapor production. Air flow and tank size alone has left my Kayfun in the drawer, not to mention the deck size.
Thanks for the blog!
Batteries in the MVP are not replaceable, they are build in...you're stuck with a useless box once the battery is dead. It's cheaper to buy 18650 batteries than an entire mod. Something to keep in mind.
I started with an ego battery, then went with a Vamo v5 and now I'm using a mechanical mod with a Kayfun Lite Plus.
