I have four (three actually, and a Protank 3 with Aero base), and they're my workhorses. I enjoy my KFL clone, and my IGO-W, but they're used on my Magneto and don't leave the house with me. For extended daily use, I have yet to find a tank I like better than my Aeros with 1.8-2.0 ohm single coils and cotton wicking.
