Excellent! I ordered two kits one for my son and one for me and I do not regret, quality and price are really good. I waited a good month for 1/2 note here my review to test these electronic cigarettes. I smoked for many years to the equivalent of 3 to 4 packs a jour.Depuis January 2014 I only use the electronic cigarette. I am quite satisfied with this eGo kit that I use in an "intensive" daily. Over time the batteries discharge slightly faster but this is a detail compared to other much more expensive purchases that I made in shops and with whom I have had different concerns. By making sure they are made to last. I just spent the water "reservoirs" 2 times to remove the little burnt taste, I wipe out the screwing places above the battery before connecting to reload and in case the light stays off despite pressure , we must think quickly press 5 once to reactivate it. I really recommend to former smokers or vapoteurs new vapoteurs.
