I am very pleased with these Clearomizern. They can be easily re-wrap, thus redefine the Ohm with each coil individually. I understand quite frankly not what some here writing this, I have of Vivi Nova to Kanger tried everything possible, these are my absolute favorites clearos. They taste good, dress well and are simple and easy to clean, they are dense and absolutely reliable. Regularly, with a sharp wound together Corner of a leaf aspirate approximately every 30-40 trains toilet paper / paper towel / paper towel briefly above purely to the mouthpiece and the condensation which forms on the silicon cap and the mouthpiece by rotating movement or drain, as the Liquid refill with cap unscrewed Mouthpiece on the silicone-based process, plus the mouthpiece tube from the bottom rub briefly dry with the paper. Thus, you always have dry conditions, it is bubbling nothing and nothing goes into the tube. A pair of handles in between, but they are worthwhile!

Have I created a stock of this evaporator at the price and enjoy with my 50/50 mix full and round taste of my flavors.
