I vaped on the Darwin for the first time on Saturday. I have been vaping for two years and have tried about 15-16 different PV's and every atomizer and cartomizer you can think of. And I can say without a doubt that the Darwin is not just a step forward in the vaping world, it is a LEAP forward. That's just how good it is. The consistency of the vaping experience on a Darwin is just better than anything on the market today.
