well my girlfriends been vaping for a bout 3 month now..well for some reason everything she vapes breaks, she started with my twist,then she got a rider robust witch still works just the button is smashed in halfway and sticks.. now her vamo isn't working,something is wrong with the center pin.. now i need to get her something,i want to buy her a provari,but i dont have the cash for one at the moment,she loves my ihybrid,but i know that wont work, i need something with long battery life and not to big,i was thinking about a box mod like the mvp. need some feedback
