Ok so my tornado nano showed up about an hour ago so I'll share my first impressions,first off the rba,put in a 316 l ss 3.5 mm coil,wicked it up and off I was,NOT IMPRESSED I must admit,you have to put sooo much cotton in there or else it will leak,yes it vapes,yes it put out clouds,but not smoothly,again because cotton is too packed in there,next time I will wick it up as another reviewer showed us in a previous thread where he puts his cotton down into the juice channels and then screws on the barrel,maybe I'll have more luck that way who knows,now on to the coil head,disappointed there as well,again it vapes,makes vapor,but not smooth at all,yes I know you might think am a little picky but I like a smooth air flow,this thing is anything but,it's scratchy at best,I have it at 60 watts and its homing out at .28,I guess my expectations were just set too high,but at the present time am glad I only ordered one and that coils where on pre order or else I would have ordered a boat load as well,maybe I got a bad coil? am only running 80% vg juice in it so it should be hitting smoothly but alas it's not the case at least not for me,any body else out there got some nano chip coils story to share? sorry for being such a party pooper guys just keeping it real:-/
