With the glut on the market of new mods,I wonder how long they will last?.....In as much as there will be a few left around for years,but when that FDA thing gets REAL BAD and they ban all new devices,and Your final puff comes to an end when Your last device fails, You are going to be left with building Your own if You can,from the remains of Your old vape mods....If You have any....Kinda like when Vaping was starting out....Mod builders unite!....Z
