it is an original Joyetech cigarette brand, not a counterfeit as there are (too) often (you can check by entering the code on the box scratch Joyetech on the site), by against the tank system is not terrible (ca depanne good, but it leaks a bit ..) therefore are planning the purchase of a clearomiseur (it costs about 5 euros), it is much more convenient and more reliable. 1000mAh battery allows satisfactory autonomy, and in the pack there are 2 so it always has a charged in case. the charger looks good. think a max load for at least 4 hours each battery before the first use to ensure a better service life.
