so for Christmas I'm gonna ask the girl for a very very nice VV mod. first thing that came to mind was the proVari. now I've made mistakes in the past jumping and ordering the first thing I have set in my mind and end up being unhappy in the long run. now I haven't heard many people say they were unhappy with this device. Im wondering is there something better out there? or devices very very similar to the proVari that are compared?
