I have just been reading about people who have felt ripped off by cruddy e-cigs. I did a small- very small - bit of research before I bought two kits from SS; one for me & one for my husband. I was happy enough with it that I ordered my pink kit. One of my SS did not fit the cartomizers, and they quickly sent me a new one. SS has been all I have tried, but I could not be more pleased. We have both quit smoking, and I have purchased 150 cartos from them. The customer service has been great. This is a good company, and if anyone is searching on ecf, I highly recommend Smoke Stik.
