If you are new to vaping, I would suggest the stardust. They don't have the leaking issues of eGo-T/C atomizers. Which is nice. And you don't have to mess around with the difficult filling/overfilling of cartos. That being said, I'm okay with people saying other setups perform better. I just think this is the best for people who want an easy experience.
+1. As a new vaper I found these to be indispensable. They've proved hassle-free and work perfectly for me. Only been a week but no leaks, dry hits, flavour suppression or excessive juice use. I do have the cartos to compare them to and prefer the clearos. I got mine from Smokeless Image who apparently use a version of the Stardusts with a different thread. I'll be buying more.
