1 1/2 years ago, I first switched to an e-cigarette. The steam output of my former ego-c was mediocre, After a few months I was up on the ego-cc, which had a better steam output, but the cleaning of the tank was very awkward (I change often my Liquid). Now, after almost a year Pyros, I rose to the recommendation of a colleague at the EVOD2.
The steam output is bombastic, it Sifft nothing and filling and cleaning of the tank runs smoothly. All in all I can recommend for beginners and professionals this e-cigarette without restriction.
