This is the replacement heating coil for the XVape Vista Mini 2. Having spare parts is always a good idea in case you lose or burn through the original. This atomizer has 510 threading, and is a quartz bucket style. Quartz is an ideal material as it can cope with high temperatures over a long period of time. It retains heat well, with less risk of breaking than other materials. This heating coil is not meant for other vaporizers, it is meant for the Vista Mini 2 exclusively.
