Hi I have the Vision Spinner 2 battery, probably the best battery before you get into APV; I am wanting a APV because I'm a huge ex smoker (only for a year and 10 months but I craved tobacco badly) my tank is a aspire nautilus. I'm wanting a APV that'd work great with my beautiful tank. Please help me choose my APV it'll be a tremendous help; I have looked at the Mvaris but I want more suggestions, thank you.
