After vaping for over six years now. I have had all the mods and every take out there, I wasted a lot of money on leaky tanks ad kits! - in the end, I juts wanted something simple, and that is what vype delivers, simple. All these Manafactureres bring out all these 'big' sub ohm devices and they have all forgot the main majority of the market, people just want efficient, good sized devices that are not bulky, and do not leak! I hope Vype carry on' on thier own path and don't follow the horrible trend of these big and ugly, leaky devices that are coming out at a rate, more than I can drink water.
