Vaporlax
Let me tell you I’ve been through many e-cigarettes, devices, mods, juices, cotton the list goes on, I purchased these because I was tired of filling juice or charging or coils, you literally take it out the package and vape, I’m a chain vapor and these last me a solid 2-1/2 to 3 days and the flavors don’t lack anywhere and taste the same until the device is dead. A little pricey but I am finally satisfied with vaping and no worries
