I bought a Vamo and it arrived today. I charged the batteries and filled a Clearomiser and the (what I think) is a Vivi Nova tank that came with it. I turned it on and played with the buttons. It's set at 3 watts and 3 volts and I double checked to make sure it was set to the No1 setting instead of RMS. The problem is that everything tastes burnt through it. I can take either tank off the Vamo and put it on my Atmos Optimus 510 and it tastes fine after a few puffs. Any thoughts?
