I finally got my hands on a map tank and while I have read all the reviews and seen all of the other tank mods out there and have made some of my own......I just wanted a freaking map tank ok? Its a very sturdy tank, no leaking in my bag, and vaping VG llike a CHAMP. Im on tank fill number 2 and so far loving it, if it keeps up for a month, Ive found my new stand by. I have some good ce2s but they run out so fast, thought I did buy the mini map because I dont like the looks of the larger tanks on smaller devices, aka a random ego battery from the tool box. For now this is my baby for my all day setup, but Im pretty sure Ill keep my cartos around for my other flavors. So far the tank is a tank, Happy vaping people!!
