Be safe and get a few of these at this price - specially if you using mechanical mods or stacking batteries.
Lithium
 ion batteries, while generally described as "safe," have been known to 
vent hot gasses and in some cases, explode. The leading cause of a 
venting battery is a hard short. 
The Vape Safe is a mechanical fuse that trips if it senses a short in the mod by shutting down the battery. The Vape Safe can also help protect variable voltage circuitry, hot springs and other circuitry inside your mod that can be damaged in the case of a hard short.

If
 the Vape Safe Protection Circuit is triggered your mod will cease to 
operate. Once a fuse has blown it is no longer operational and the Vape 
Safe will then need to be replaced
