I have tried most of the brands and the ECigarettes Starter Kits are by far the best experience I have experienced. The last brand I tried was not good and while it was better than some others, the flavors were just awful. I also had an issue with a battery and had to really create a stink to get them to exchange it.
So far the ECigarettes Starter Kits have been great. The batteries last all day (I got 2 batteries) and the cartridges are the best tasting I have ever experienced.
Having tried virtually every brand out there, I rank ECigarettes Starter Kits as the top product out there. Hope this info helps... Good luck to all.
