Ok so i watched some videos on the tube about micro coil set ups in the kayfun 3.1 so i decided to try it now i will tell you i didnt find anything i liked about it at all there were many cons about it and i will list them. 1. Uses more wire 2. Takes longer to heat up and get vapor from it 3. It continues to sizzle juice for like 10 seconds after releasing the button 4. Uses more juice and battery 5. For some reason it taste like crap probably cause it is retaining too much heat and not letting much air cool the coil causing everlasting burnt taste. So i am in my truck now at college waiting for class to start as i type this thread. But i am hardly touching my ecig and the first thing i am doing when i get home is building a regular coil set up.. i will never be making a compressed micro coil again i dont like anything about them so i would be happy to hear what you guys think and if you have had a simmilar experience with micro coils.
