I have swore by the iclear 16 dual coil clearomizer 2.1 ohm and people would tell me you gotta try this 1 or that 1 you will like it better and you want the lower resistance, but me thinking I knew better because ive been using these on my 1000mah twist for so long was not going to try (my ego) well I finally did try some new one's after more research and found out that to get what I wanted out of my e cig there are a few different things you can do, so I got me a kanger mini pt/3 bottom feed dual coil and found out that gave me what I was looking for which along with using 100% vg and that 1.5ohm coil i got the bigger clouds and a warmer hit. I'm not knocking the iclear16 because it is an excellent clearomizer but always research and that is how I have started learning so much, don't just take the salesman word for it because 9times out of 10 they have no clue.
