For the price and the reviews pretty good I started on the case, indeed: just gives confidence packaging? Ok! The instructions in French? Ok! Its simplicity? Ok! So I charged the battery, put the e-liquid, and pressed the button 3 times to start it lights up LED "constant" for half sconde then flashing, then nothing! When pressed a second time it happens the same and by the 3rd time against anything .. Maybe the battery is dead, I commend the Re-charge and the threads of the charger remains in my hand . Honestly I did not need such a story! Look elsewhere! FLEE SAME ..
