I have the Vari-Tube v1.5 (lava tube want a be) made be Young June Company. My question is when I check the ohms on my Vision Ego (stardust) Clearomizer V2 with the long wicks and get different reading. The stardust i am using is 2.1 - 2.4 ohms. When I check it with the vari tube it reads 2.3 ohms than I check it again and it says 2.9 ohms so I take a toot and than it's back to 2.2 ohm. I notice that whenever i set the voltage to 4.0 or over I start to get a burnt taste. If I put the same clearomizer on the ego twist and set it to 4.0 and over no burnt taste.
