Wow, an overwhelming turnout for mods! And I totally agree. My first foray into full-time vaping when I quit the stinky sticks was with a pen. It was a Joyetech eGo AIO, & the window glass inexplicably cracked about 2 weeks after I bought it at my local B&M.
They were kind enough to take it back & give me store credit, for which I was thankful.
I hated the thing anyway: it got way too hot too quickly, & coils were expensive (in my opinion). Good riddance.
Mods give me the versatility of building & savings I so very much enjoy. They are better-looking, have longer-lasting batteries which may be swapped out, have options to customize the vaping experience, & a crapton of other advantages too long to list here.
I'm never going back to those f**king sh***y-a** god***m piece of sh** pens.
Unless it's free. In that case...yay?
Mods 4 lyfe, y'all!!! LOL
