I just had my new Kroma Z delivered today. This thing is great. I am using the 1.6 coil at 10 watts. I am using the regular airflow ring almost totally shut off, and its about the same vape as the beep with airflow almost shut down. I like it better than the beep because it is light weight. To me that was the only thing holding the beep back, was the weight of it. I tried the precision mtl airflow ring, but it was too tight. The vape did not seem that smooth, seemed like it needed a bit more air to perform correctly. I know there is a lot of z coil devices out there now, but for a small compact device, that does not weigh much, with a 3000 mah battery, it truly is hard to beat. I love the fire bar, reminds me of the older sinious p80. This will finally put my justfog mini fit to bed, as I have been waiting for something small that vapes like a pod from innokin using the z coils. Well done Phil, Dimi and Innokin! I just ordered a 2nd one just to have a back up, I am assuming 3000 mah on 10 watts should get me through a day. If you want a smaller, not a true pod with different coils and airflow options, I suggest this kit.
