My Legacy mini came today. I put a charge on the batts. got the tank all set and did a little vaping. "nice" After a little time with a ego twist I decided I didn't need VV. All the jucies I like taste best at 3.7v with 1.5-2.0 carts. So with the VV out of the way I got closer to making a choice and a good one I did. tank went together like a dream. I'm happy.
