I just bought this used and was told this was a vivinova, although it looks different from the vivinova's I looked up. It's set at 2.8ohm, I believe and I tried it at 4.5, 5, and 6 watts. At 5+ watts it just felt like warm air, but there is a lot of air when I am pulling and feels like more air and noise than actual vapor. And the vapor cloud isn't as big as I was expecting. I am using some juice that I was given, not sure from where, but it tastes kind of weak. It's green apple. But could it be the tank or the juice that is giving unsatisfactory results? I am sure I need to invest in a good tank. The ohms option hasn't made much sense to me yet, but have a feeling that may be what I need to learn about. Still unsure of what tank to get just yet, but that will be my next purchase. Here's a pic. I think it is supposed to have a new wick as well.
