Exxus Tap VV Cartridge Vaporizer by Exxus Vape
4/18/2019
Its an awesome battery for pre-filled cartridges and the carts seem to last longer with the exxus.
Easy to use and no buttons to push. The 10 sec. preheat option is nice for a lung filled hit, but you can just draw to hit also. The four different temperature settings are nice added bonus and color coded, from 3.3v-4.2v.
I highly recommend.
