OK...
now get yourself a backup. The Boss from SmartVapes is an inexpensive "mechanical" mod that is, quoting my review: "Sleek, beautiful, and exceedingly well built! Metal button (the button is not clicky but it is very smooth) with led and 5-click on/off! The chrome cap on the bottom is a nice classy touch. The paint is flawless and the threads in the body are insanely smooth! Compact and easy to use.
C’mon, a sweet, quality 18650 mod with all this and short circuit protection built in (no need for a Vape Safe) for this price? BUY IT!"

EDIT: You have the 18650 batts already, right?
