This is my 1st post. The first device I tried was a vision spinner with a counterfeit kanger protank. I didn't know it was counterfeit until I went to a real shop and looked at other protanks because mine sucked, and realized they all said kanger on the base of the tank. 1st lesson learned. So then I bought the itaste 134. The tank that came with it did have good flavor, but leaked and gurgled. So I tried the whole line of iclears. Same result. After reading online, I bought my 1st real tank system, the kayfun 3.1. Awesome. New hobby. Building coils is pretty easy, but I'm a newbie, so I hit the Web again. Now I also have the lite plus. They have great flavor and nothing compares. So I bought a couple rda's. But dual coils are useless on the itaste134, they take too long to heat up because gotta keep it above .8 ohms. So I've been playing with single coils, and with the itaste134 at 12.5 watts it's still not enough. Is it because it's regulated and 12.5 watts isn't enough power? So now I want to move to a mechanical and people say the nemesis is a good clone. Is it a whole different experience? Is a mech gonna give me that extra power I'm looking for? Is the itaste134 not really for rda's? It works ok with the kayfun but I think I can get more of of them as well. Please help, thanks
