And they are better than ever! I rebuilt 4 heads using 2mm ekowool wrapped with 30 gauge kanthal with the goal to achieve different resistances and ended up with 1.4ohms, 1.9ohms, 2.3ohms and 2.7ohms. Currently vaping the 1.9ohm head at 10.5watts on my SVD and it's great! Flavor is definitely cleaner (I can actually taste the pomegranate in "Full House" by Villain Vapors), throat hit is smoother but still very noticeable and vapor production is more dense. Really liking the ekowool since it can handle more power and not worry about it burning. Good thing I have extra batteries
